I have a S8 Enterasys where I lost my OSPF neighbors with our Border router. When I do a sh ip ospf neighbors, it shows it in a ex-state. I have clear the process, taken it out and re-enter, but still on ex-state. I can ping the border router but can't get that connection. I have checked the interfaces, and uplink ports, all looks good.
Outside border interface:
interface vlan.0.100
description "insidevlan"
ip address xxx.xxx.xxx.x 255.255.255.240 primary
no shutdown
exit
Core interface:
interface vlan.0.302
description "InsideFirewall"
ip address xxx.xxx.xx.x 255.255.255.240 primary
vrrp create 2 v2-IPv4
vrrp address 2 xxx.xxx.xx.x
vrrp priority 2 254
vrrp host-mobility 2
no shutdown
exit
V302 goes to a C5 switch which then goes to the inside FW, goes out through outside FW to the border (S4 router) V100.
This all started when we converted our FW's to layer 3. Everything was working fine, except for some VPN issues which we than reverted back. Now the neighbors don't connect.
