question on GRE tunnels
Posted on 2011-10-01
Hi , i have a cisco 2811 router with the following tunnel
description connection to Site B
ip address 10.10.10.10 255.255.255.252
ip flow ingress
tunnel source fa0/1
tunnel destination 220.127.116.11
tunnel key 529
I added a second 2811 and did HSRP
when it comes to creating the tunnel to site B on this router
source can be the same fa0/1
destination will be the same 18.104.22.168
what about tunnel IP ? can it be the same ?
Tunnel key will be different ( i.e 530 )
Any inputs would be appreciated... I am not sure about the tunnel IP...
