Checking split horizon status with IPv6 In a frame relay multipoint topology where the routers are running RIP, we know that RIP by default keeps split horizon on with IPv6 and we go into the RIP process an use no ip-split horizon to disable it. But my question is, what command do you run to check whether split horizon is enabled on disabled on that interface with IPv6? Much thanks!

For Cisco devices, it is pretty easy:


Router> show ipv6 rip
RIP process "process1", port 521, multicast-group FF02::9, pid 62
Administrative distance is 120. Maximum paths is 1
Updates every 5 seconds, expire after 15
Holddown lasts 10 seconds, garbage collect after 30
Split horizon is on; poison reverse is off
Default routes are generated
Periodic updates 223, trigger updates 1
Interfaces:
Ethernet0/0
Redistribution:
Redistributing protocol bgp 65001 route-map bgp-to-rip


Notice the `Split horizon is on;` in the output.

Cisco has lots of documents on this sort of thing, e.g. Chapter: Implementing RIP for IPv6.
