VTI beween central site 7606 and remote offices, EIGRP issue?
Have this weird issue with VTI tunnels on a 7606 running 12.2(33)SRE1 and several remote offices
1. When IPSec communication is established between two remote offices (this is with two VTI tunnels to the 7606), one remote office fails to connect to the other office unless we send the whole EIGRP routes belonging to the remote offices. When only the 0.0.0.0/0 route is sent from the 7606 to the remote offices, the remote offices can´t communicate between each other.
2. When one remote office is VTI and the other office is a plain GRE tunnel they can´t communicate at all unless we add the tunnel checksum command at either side but we would like to avoid it due to resource consumption
Any help is grately appreciated since we don´t want to send the whole EIGRP table to each and every remote office.
