IPSEC w/ ISL VLAN

I am having a problem getting IPSEC to work on a router that is used as a intra-VLAN router. The "crypto map toShipping" is bound to fast ethernet 0/0.4 (ip address 208.50.0.163) on a 2621. If I do a "debug crypto ipsec" I see "1w0d: IPSEC(validate_proposal): invalid local address 208.50.0.163" over and over. Any ideas or directions would be of great help!! Thanks in advance!

Re: IPSEC w/ ISL VLAN

try create a loopback interface, say loopback10, configured with a valid address for your ip network.

(making sure you can access the ip address from the remote router!)

Then try the command

crypto map toShipping local-address Loopback10

then reboot or clear crypto isa and clear crypto sa at both ends at the same time...

Re: IPSEC w/ ISL VLAN

thanks for the reply, I opened a TAC case and got a resolution. Your pretty much right on the nose except Cisco personel had me enter the ethernet interface as the "local-address" via the command "crypto map toShipping local-address fast 0/0.4". It worked! Thanks for the reply, once again!
