IPv6 routing to another interface
- by Robert
I'm trying to get an IPv6 enabled router to forward data from one interface to the other and I'm having issues.
When following this example (http://www.cisco.com/en/US/tech/tk872/technologies_configuration_example09186a0080ba6106.shtml) I am able to get full connectivity between all 3 routers in my simulator. However when I try to use only 1 router; I can't get connectivity to the other interfacs on the same router.
My PC is directly attached to FA 0/1 and it can ping the router's interface. However it can not ping any other interface on the router(which unless I'm missing something it should be able to do). The router on the other hand can ping everything. I thought static routes might help; but the router already has routes for everything.
I'm thinking the packet should come in; router looks up the destination in it's ipv6 routing table and then realizes it's for itself, and should respond. I thought maybe it couldn't respond directly; so I tried pinging a device like 2001:0000:0000:1000::2, but i don't get a response.
I'm running on IOS 12.4.
I'm missing something(hopefully simple), but I just can't see what it is. With only 1 router; how do I enable my PC to talk to the other subnets? Thank you in advance, Robert
Topology:
R1
FA 0/0:
2001:0000:0000:0000::1/52
FA 0/1:
2001:0000:0000:1000::1/52
FA 1/0:
2001:0000:0000:2000::1/52
Loopback 0:
2001:0000:0000:3000::1/52
PC:
2001:0000:0000:2000::2/52
PC plugs directly into FA 1/0 on the router.
