Change ipsec peer ip address

jamesbruce

Haven't done this in a while and am a little rusty. Need to change the ipsec site to site peer address on a tunnel, a one router is changing locations/ip address.

The current cryptomap config is :

crypto isakmp policy 11

encr 3des

hash md5

authentication pre-share

!

crypto isakmp policy 12

hash md5

authentication pre-share

crypto isakmp key abc12345 address 206.169.4.20

crypto isakmp key XXXXX address 66.194.7.3

crypto isakmp key XXXXX address 66.162.45.164

crypto isakmp key XXXX address 168.215.214.202

!

!

crypto ipsec transform-set set1 esp-3des esp-md5-hmac

!

crypto dynamic-map dynmap 20

set transform-set set1

match address 120

!

!

crypto map map1 local-address Serial1

crypto map map1 client configuration address initiate

crypto map map1 client configuration address respond

crypto map map1 11 ipsec-isakmp

set peer 206.169.4.20

set peer 66.194.7.3

set peer 66.162.45.164

set peer 168.215.214.202

set transform-set set1

match address 120

The current address of the router that will be changing is 66.162.45.164

I think all I have to do once they get the router at the other end configured is to change the 66.162.45.164 address in the cryptomap to the new ip address, is that correct?

Hi,

Yes, that is correct. Also, make sure that you configure the crypto isakmp key with the correct Pre shared key and IP Address.

set peer NEWADDRESS

crypto isakmp key XXXXX address NEWADDRESS
