Hello,One more question. I'm trying to configure 2x6509(VSS+MEC)+external FW. I'm confused about VRF approach. Which variant would be better? Which advantage and disadvantage every one have:1. VRFx: [access switch] -- vlan 101 -- [VSS] --- vlan 102...
I've resolved this issue by changing IOS to 24-15.T13 (Cisco 871, 2811). Aslo I use "crypto isakmp keepalive 120 10 periodic" command. But I haven't found solution for Cisco 881 yet (15.1.2T1 doesn't suit).
