Hi Jason, so i must to have two frame-relay map into each serial interface? and
, the neighbor command under eigrp process, must to match with the remote IP ad
dress?
I dont't know what is wrong in my configuration, cause when i start the eigrp d
ebug, nothing appears in my screen.
Why when i type "show run" the eigrp process doesn't appear ?
Follow my actual configuration:
R1)
!
interface Serial1
ip address 138.1.13.1 255.255.255.252
encapsulation frame-relay
cdp enable
frame-relay map ip 138.1.13.1 113 broadcast
frame-relay map ip 138.1.13.2 113 broadcast
no frame-relay inverse-arp
end
!
router eigrp 50
no auto-summary
neighbor 138.1.13.2 serial 1
R3)
interface Serial1/4
ip address 138.1.13.2 255.255.255.252
encapsulation frame-relay
frame-relay map ip 138.1.13.1 706 broadcast
frame-relay map ip 138.1.13.2 706 broadcast
no frame-relay inverse-arp
end
!
router eigrp 50
no auto-summary
neighbor 138.1.13.1 serial 1/4
!

No. You have no mapping to the remote IP address, only the local. You
would
also need
frame-relay map ip 155.10.123.1 102 broadcast
on router 1
and
frame-relay map ip 155.10.123.2 102 broadcast
on router 2.
