this is not a help by a link but only request for information about dot1q or isl, i would like to exchange vlan tagging between a cisco cluster (4506) and a cajun avaya core switch. i tried every kind of conf, but i see only one solution:
a port for every vlan connected between each other by cisco and avaya, but i have almost 70 vlans so too much port (the double).
i have configured many clusters by trunk port with enc dot1q and vtp domain, and the vlan database is correctly replicated by the cluster-members of vtp domain.
if you have some docs you think it can helps me, please keep me involved.
