why if i have a frame-relay interface configured with no frame-relay
inverse-arp and a map statement with the broadcast command - repeat on side B
I cant ping my own serial - if router 1 had an ip of 1.2.3.4 and 2
had 5.6 7.8 both configured on s0 as described above r1 can ping r2s
serial but not its own??
I was planning on using a ping trace on the ccie lab to test connectivity
if anyones curious heres the show run fron R1 and R2
R2 - without EIGRP its a total no go - no connectivity
