EIGRP IPv6 - Redistribution
Redistribution
EIGRP (Enhanced Interior Gateway Routing Protocol) IPv6 Redistribution is a critical capability that facilitates the exchange of routing information between EIGRP and other routing protocols in an IPv6 network. In complex network environments where multiple routing protocols coexist, redistribution ensures seamless communication and cooperation between routers running different protocols. EIGRP supports IPv6 redistribution with various routing protocols, allowing administrators to share and integrate route information effectively. Careful configuration is essential, as administrators need to map and filter routes to prevent issues such as routing loops or suboptimal path selection. Proper IPv6 redistribution setup ensures that routers employing different routing protocols can collaboratively contribute to the network's routing information, fostering optimal path selection and efficient network connectivity. EIGRP IPv6 Redistribution thus serves as a vital tool for network administrators to integrate diverse routing protocols and maintain a cohesive and efficient IPv6 routing infrastructure.

Task 1: Configure IPv6 EIGRP Redistribution
Step 1: In the configuration mode of router configure 4 loopbacks with IPv6 network address in sequence
R1:
interface loopback 101
ipv6 address 101:101:101:: 101/64
exit
interface loopback 102
ipv6 address 102:102:102:: 102/64
exit
interface loopback 103
ipv6 address 103:103:103:: 103/64
exit
interface loopback 104
ipv6 address 104:104:104:: 104/64
exit
Step 2: Redistribute these connected network in IPv6 EIGRP process
R1:
ipv6 router eigrp 100
redistribute connected
exit
It will redistribute connected network on which IPv6 EIGRP is not sending updates
Task 2: Verification: Step 1: Verify route in neighbors router routing table by following command:
R2#show ipv6 route
