Hi all,

I am planning to configure multiple site-to-site tunnels cisco 2811 ISR router

if possible how we can bind the tunnels with the interface .

in the normal way like

r1(config)#interface s1/0

r1(config-if)#crypto map R1

r1(config-if)#crypto map cisco


does it work ?

Plase suggest ...

I hope i understand you correctly.

Yes you can create multiple VPN tunnels but you don't have separate crypto map names.

So you choose one crypto map name eg.

crypto map vpn-set 10 ipsec-isakmp

set peer x.x.x.x

set transform set xxxx


Then your next tunnel would be

crypto map vpn-set 20 ipsec-isakmp

set peer y.y.y.y

set transform-set x.x.x.x


So you use the same crypto map name and create multiple tunnels by using numbers.

Note, you don't have to go 10, 20, etc.

You can use 1,2,3 etc. if you want, it's up to you.
