Describe Transit BGP Networks – Filter incoming and outgoing BGP updates routemaps – Influence BGP route selection – Monitor and troubleshoot BGP filters – Implement non-disruptive BGP policy changes – Limit the number of routes received from a BGP neighbor
A BGP routing policy has been created using route maps. The command route-map TEST permit 10 is part of the configuration. What does the argument 10 indicate? It identifies the access list number to be used by the route map statement. It identifies the position of the route map in relation to other instances. It indicates the local preference to be set for routes that match the route map. It indicates the metric to be set for routes that match the route map. It specifies the route map to be used on autonomous system 10....
International Travel Agency maintains two WAN links from the West Tasman (i.e.,
Westaman) site to its core network 10.0.0.0 /24.One link is full T1 (1.544 Mbps), and the
other is a fractional T1 with a capacity of 768 Kbps. Under OSPF, West Tasman prefers
the Full T1 link by virtue of its higher bandwidth (and lower cost). However, the Network
Operations Center has decreed that all traffic from the 192.168.72.0 LAN bound to
10.0.0.0 /24 should use the slower fractional T1 link until further notice. You are to apply
this policy by configuring a route map on the West Tasman router....
Administering Cisco QoS in IP Networks discusses IP Quality of Service (QoS) and
how it applies to Enterprise and Service Provider environments. It reviews routing
protocols and quality of service mechanisms available today on Cisco network
devices (routers, switches, etc.).This guide provides examples and exercises for a
hands-on experience to give you the background and necessary details to implement
these capabilities in your network today.
Link-State Routing Protocols.
Describe the basic features & concepts of link-state p routing protocols. Distance vector routing protocols are like road signs because routers must make preferred path decisions based on a distance or metric to a network. Link-state routing protocols are more like a road map because they create a topological map of the network and each router uses this map to determine the shortest path to each network. The ultimate objective is that every router receives all of the link-state information about all other routers in the routing area.
What is an advantage of the NAT-PT technique for transitioning between IPv4 and IPv6? All mappings are static. Globally routable IPv4 addressing is not required. DNS is not required. No configuration is required on end nodes. How do IPv6 enabled routers handle packet fragmentation? IPv6 routers do not perform packet fragmentation. OSPFv3 has a mechanism for determining the optimal packet size and dynamically adjusting the packet size. IPv6 routers do not perform packet fragmentation. CDP is used to discover the correct packet size for any given traffic flow....
Explain the purpose and use of seed metrics in route redistribution. Describe how to redistribute routes into RIP, OSPF, EIGRP, and IS-IS. Explain how to verify route redistribution. Explain how to control routing updates using the passive-interface default command and route maps. Describe new DHCP commands.
Link-State Routing Process
1. Each router learns about its own links, its own directly connected networks.
(Interface is “up”)
2. Each router is responsible for meeting its neighbors on directly connected
networks. (OSPF Hello packets)
3. Each router builds a link-state packet (LSP) containing the state of each
directly connected link. (neighbor ID, link type, and bandwidth)
4. Each router floods the LSP to all neighbors, who then store all LSPs
received in a database.
Neighbors then flood the LSPs to their neighbors until all routers in the
area have received the LSPs.
Objectives: Describe the primary functions and features of a router. Scenario: Using the Internet and Google Maps, located at http://maps.google.com, find a route between the capital city of your country and some other distant town, or between two places within your own city.
Objectives: Test Network Connectivity Using Ping, Trace a Route to a Remote Server Using Windows Tracert, Trace a Route to a Remote Server Using Web-Based and Software Tools, Compare Traceroute Results.
We have all heard the saying "It’s what’s inside that counts" at some point in our lives. In the world of
networking Cisco’s Internetwork Operating Systems (IOS) has taken that saying to heart. The very
core of Cisco Systems phenomenal success is the breadth of services provided by the Cisco IOS
No two networks are exactly alike. There are connectivity requirements that differ between healthcare
and manufacturing, entertainment and shipping, finance and telecommunications. Each of which has
different security issues.
This book is about network policies and how to implement those policies using Cisco IOS
access lists. I present a way to think about access lists and network policy, describe how
access lists are built, and give examples of how to apply those access lists in different
situations. Along the way, there are a number of sidebars and notes about concepts and
information important to using access lists, and at the end of the book, there are appendixes
with useful reference material.
A / Aims and Objectives : By the end of the lesson , Ss will be able to listen and match the places in the box to their correct positions on the map . B / Teaching aids : Cassette , a route map … C / Procedure : I / Warm up : Quiz what is this place ?
- Ask questions and call the student who puts his / her hand up first to answer - Tell Ss each place consists of 3 questions ; 3 points for the first question , 2 points for the second question...
- Step 1: Tạo một danh sách địa chỉ IP sẽ được dùng để ánh xạ với các địa chỉ loopback của router CE. - Step 2: Tạo một route map sẽ được dùng để ánh xạ với các địa chỉ loopback của router CE với danh sách prefix và gán các giá trị client RT vào những route đó. - Step 3: Đưa các route map vào những route được xuất ra từ các VRF của khách hàng với câu lệnh: export route-map.
When it comes to planning our lives and our careers and
then trying to make the plan come true, most of us live in a
fog of confusion. Few have a destination in mind. Even fewer
have a route map.
We have a vague sense about getting along and doing
well but few of us are sure exactly why and spend periods of
our lives slightly or very discontented.
Inverse ARP is on by default
Automatically maps the IP address of the devices at the other end of the PVCs to the local DLCI number.
Split horizon is disabled by default on Frame Relay physical interfaces.
Routes from Router R2 can be sent to Router R3, and vise-versa.
Note: Inverse ARP does not provide dynamic mapping for the communication between routers R2 to R3 because they are not connected with a PVC; this must be configured (mapped) manually
Our desire for the event notiﬁcation service to be general purpose also compli-
cates the routing problem for the service. In particular, we assume that objects
of interest have no knowledge of interested parties. Therefore, event notiﬁca-
tions cannot be addressed and routed in the same, relatively simple manner
as, for example, an electronic mail message. Moreover, we cannot assume any
particular locality of objects of interest and interested parties, which is a fact
that bears a strong relationship to the server topology issue.
