[nsp] Help with tunnel

[james edwards]

I want to set up GRE tunnels from my NOC router to each of the colos, so I
can number
gear that does not need a public IP out of the net 10.123.0.0/16. The 2
routers below
are not directly connected.

I am not carrying the 10.123.0.0/16 le 24 prefix in my IGP, EIGRP.
I suspect this is why they are up/down but I wanted to check on make sure
my configs are correct, first.


NOC router:
!
interface Loopback99
 ip address 10.123.100.1 255.255.255.0
!
interface Tunnel0
 description Tunnel to sf-colo
 ip unnumbered Loopback99
 tunnel source Loopback99
 tunnel destination 10.123.3.2
 tunnel key xxxx
tunnel path-mtu-discovery

ip route 0.0.0.0 0.0.0.0 ethernet0/0
ip route 10.123.3.0 255.255.255.0 Tunnel0


Colo router:
