IPv6 Routing

1. Enable IPv6 Routing To enable IPv6 routing, use: R(config)# ipv6 unicast-routing This will enable the router to send RAs unsolicited or in response to RS messages. 2. Static Routing ! Directly attached static routes: R(config)# ipv6 route IPV6-PREFIX/IPV6-PREFIX-LEN OUT-INTERFACE [AD] ! Recursive routes: R(config)# ipv6 route IPV6-PREFIX/IPV6-PREFIX-LEN IPV6-NEXT-HOP [AD] …

Routing over Frame Relay

1. Topologies 1.1 Full Mesh The simplest Frame Relay topology is the Full Mesh topology, where each router has a dedicated virtual circuit to another router. Unfortunately this design is rarely found in real life because each additional circuit costs. Of course, having so many circuits available makes it easy …

MPLS 101

1. Labels MPLS (Multi Protocol Label Switching) adds a 4 Byte header between the Layer 2 and Layer 3 header for each label. The header has 4 fields: 20 bits – Label – locally significant on the link (similar to Frame Relay DLCI) 3 bits – EXP – used for …

RIP 101

1. Starting the routing process R(config)# router rip R(config-router)# network NETWORK-ADDR In RIP there is no wildcard option when configuring the network command. The NETWORK-ADDR will always be considered a classful address and will match all interfaces that are in the same classful network: R(config-router)#network 172.16.23.45 R1(config-router)#do sh run | …
