I’m proud to be studying networking in general, and Cisco in particular. Showing RIPng configuration information show ipv6 protocols We can see which interfaces are participating in RIPng show ipv6 rip RIP_ZONE displays various information about the RIP_ZONE process Debugging RIPng debug ipv6 rip – see that link local addresses are used in multicasting – destination address is multicast FF02::9 ———– In my home TSHOOT lab, R4 has only fa0/0 in RIPng. – The split horizon rule is a loop avoidance technique that prevents a route from being advertised out the interface through which it was learned. Route redistribution into RIPng We’ll configure it on router R4, because here it is the ASBR between OSPFv3 and RIPng. We chose metric 10 because Seed metrics shoul...
