Hi group,
i got this concept ques for ipv6:
[r3]---------------[r1]-----|eth0
r3 and r1 is connected over Frame relay
r1 and r3 runs ebgp
question1:
why r3 sees different next hop for r1's eth0, when
using "sh ipv6 route" and "sh bgp ipv6"?
i need to map the next-hop address specified in
"sh ipv6 route" for it to work
question2:
will it matter when the link between r3 and r1 is:
-point-to-point
-NBMA
-multiaccess: ethernet
Thanks for any feedback
Lim
