Hi,
if the other router only accepts a version 2 peer than you have a problem.
The cisco by default will always use a version 1 peer it it initiates the peer.
In this case the most simple way to fix it is to make the cisco promiscuous and let the other router open the connection. We will follow whatever type of peer it wants, version 1 or version 2.
The only active way to open a dlsw version 2 peer on a cisco router is to have CSCeb47150 included.
It is in 12.2(19) and higher and in 12.3(4) and higher. With this included you can configure the v2-single-tcp statement on the remote peer.
this is designed to come around problems with NAT where we have trouble with the order of ip addresses to bring down the second tcp session for a version 1 peer.
I dont know if this would work in your environment. It is designed for VPN/NAT environments and the head end should be promiscuous or passive. You would need to try if this helps in your case.
However you should also talk to the support of your remote routers to find out why they have trouble with a version 1 peer.
thanks...
