-----------------
SImilar in operation to EIGRP
- transport via protocol 88 to unicast & multicast FF02::A
Enabled at link level
ipv6 eigrp [ASN]
Global process disabled by default
- no shutdown under global process
- IPV4 formateed router id needed
int fa0/0.146
ipv6 eigrp 1
ipv6 router eigrp 1
no shut
sh ipv6 eigrp neighbors
sh ipv6 eigrp topology
EIGRPv6 use the router configuration command “distribute-list prefix-list” to perform route filtering; and when configuring route filtering the “route-map” command is not supported

OK so we enable eigrp on the interface
r5(config)#int s0/0/0
r5(config-if)#ipv6 eigrp 1
enable the router eigrp and do a no shut
r5(config)#ipv6 router eigrp 1
r5(config-rtr)#no shut

R5 is not getting the routes the only way i could get the routes was to do a map to
the link local address
r5#sh run int s0/0/0
