This is partial output of "Show running-config" on my Cisco 2650:
router eigrp 100
no eigrp log-neighbor-changes
ip route 0.0.0.0 0.0.0.0 10.10.1.253
ip route 10.1.5.0 255.255.255.0 10.10.1.30
ip route 10.1.6.0 255.255.255.0 10.10.1.30
We used to have frame relay network, and 192.168.12.0 were the routes on this network. It was replaced by a VPN/T1 WAN, where our Cisco concentrator's internal IP is 10.10.1.30. As the migration was done, individual ip route entries were added to 10.10.1.30, and others (to 192.168.12.xx were removed.
Can someone please explain EIGRP? Was its purpose only to redistribute IPs to the frame relay? Can it be removed?
This Cisco 2650 router is the default gateway at my office, where the concentrator is located. We are having fragmentation errors at my location (when packets are fragmented, only the first fragment is transmitted), and I am wondering if it is caused by the remains of the old frame relay.
