In your first config set on R2, you're using the frame-relay interface-dlci
command.
When you do a "debug ip packet" on both sides with the first config, I bet
you'll see things...
R1 will send out the ping just fine. R2 will come up with an "encapsulation
failed" error.
When you do a "show frame map" on R2 you'll see nothing.
With your second config set put in, if you do a "show frame map" you'll have
an entry in there, and therefore things will work. L3 --> L2 mappings are
important!

Hi,
Hope someone can explain this to me....
If I have:
r1(multipoint) ------------ r2(physical interface)
If I configure this, r1 and r2 can ping each other.
r1#sh run | b 6/0
interface Serial6/0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial6/0.123 multipoint
ip address 172.16.123.1 255.255.255.0
frame-relay map ip 172.16.123.2 102 broadcast
frame-relay map ip 172.16.123.3 103 broadcast
no frame-relay inverse-arp
r2#sh run | b 1/0
interface Serial1/0
ip address 172.16.123.2 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay interface-dlci 201
no frame-relay inverse-arp
If I configure like this, I got no problem in connectivity...
r1#sh run | b 6/0
interface Serial6/0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial6/0.123 multipoint
ip address 172.16.123.1 255.255.255.0
frame-relay map ip 172.16.123.2 102 broadcast
frame-relay map ip 172.16.123.3 103 broadcast
no frame-relay inverse-arp
r2#sh run | b 1/0
interface Serial1/0
ip address 172.16.123.2 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
frame-relay map ip 172.16.123.1 201 broadcast
no frame-relay inverse-arp
What's wrong with the first set?
