Using loopback address to identify IPsec peer

[crhodes]

I have two IOS routers and would like to use the loopback address on the remote router as the peer address as recommended in papers such as "Configuring IPSec with EIGRP and IPX Using GRE Tunneling".

On the local router, I identify the remote router via its loopback address, and on the remote router, I configure crypto map MYMAP on interfaces S0/0 and BRI1/0 (with nothing configured on the loopback interface other than IP address)

When I establish an IPsec tunnel from the remote router, it uses the interface on S0/0 as its source address.

I tried configuring crypto map MYMAP on loopback0 instead of S0/0 and BRI1/0 but this didn't work.

How can I get the remote router to use its loopback address as the source address?

Thanks in advance for any assistance offered.

Try using "crypto map local-address loopback 0"

Thx, that worked!

I poked around the config options prior to the original post, but missed that one.

Many thanks
