lab 8-1 2...

you gotta turn on cef and unicast routing for ipv6...wasn't my idea...

ipv6 unicast-routing
ipv6 cef

put ospf on the interfaces...

r1

int lo0
ipv6 ospf 1 area 0

int s1/1
ipv6 ospf 1 area 0

int s1/3
ipv6 ospf 1 area 0

r2

int lo0
ipv6 ospf 1 area 0
 
int s1/1
ipv6 ospf 1 area 0

int f0/0
ipv6 ospf 1 area 0


r3

int lo0

ipv6 ospf 1 area 0

int s1/3
ipv6 ospf 1 area 0

int  f0/0

ipv6 ospf 1 area 0

 r1#sh ipv6 ospf neigh

they should all have three ospf entries...
