Hi kc,
I am not aware of any problem connecting p2p subif to phy interface
For p2p subif:
- you need to specify the DLCI via 'frame-relay interface-dlci 104' otherwise the DLCI are assigned automatically to the phy intf
- no need for inarp nor for map, because its treated as a phy p2p interface
For phy intf:
- as inarp is disabled you need the map
This is my config:
r1#show running-config | begin Serial0
interface Serial0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial0.14 point-to-point
ip address 172.16.14.1 255.255.255.0
frame-relay interface-dlci 104
r4#show running-config interface serial 0
interface Serial0
ip address 172.16.14.4 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.16.14.1 401 broadcast
frame-relay interface-dlci 401
no frame-relay inverse-arp
end
My 2 cents,
Luca.
