IPV6 Routing Issue

Joshuabowers · ‎05-08-2017

Hello,

I re created my topology in the packettracer program by cisco. My issue is that the PC can not ping a 2001:db8:Acad:B::1/64 address on the simulated ISP router. I tried multiple static/default routes on router0 and router1 with not luck. Can you look at my packet tracer file and explain what the issue is. I added a extra .zip to the file path so I can upload the file.

router 0 is a simulated ISP has one route for the R2 IPV6 address

router 1 is the Border router for Eigrp. has default route to ISP

Router 2 is a internal router

The two routers Router0 & Router1 have static default route using interface :

ipv6 route ::/0 FastEthernet1/0

So when Routers0 want to contact a device that is not directly connected (the ping reply in your case), he send an NS (Neighbor Solicitation) to resolve the ipv6 address requested (like ARP in IPv4).

Router0#*mars 1 01:21:28.576: ICMPv6-ND: Sending NS for 2001:DB8:ACAD:12::1 on FastEthernet0/0

Router1#*mars 1 01:21:28.613: ICMPv6-ND: Received NS for 2001:DB8:ACAD:C::5 on FastEthernet0/0 from 2001:DB8:ACAD:12::1

But he doesn't have any answer ...

Try to configure static default routes using IPv6 address, it should work =>

ipv6 route ::/0 FastEthernet1/0 FE80::2

or

ipv6 route ::/0 2001:DB8:ACAD::X
