Hi ALL,

I am reviewing FR and find that I cannot ping the router own FR serial. I
can ping from other routers via the FR but I cannot ping itself from the
router. I can ping other own serial interface from the router too. Anyone
would have suggestions or reason why I can't ping? Below is my config.

R3 config
host r3
!
int s0
 ip address 192.168.252.3 255.255.255.0
 encap frame
 frame-relay map ip 192.168.252.4 123
 frame-relay map ip 192.168.252.5 124
 no shut
!
int s1
 ip address 192.168.250.3 255.255.255.0
 no shut
!

R4 config
host r4
!
int s0
 ip address 192.168.252.4 255.255.255.0
 encap frame
 frame-relay map ip 192.168.252.321
 no shut
!

R5 config
host r5
!
int s0
 ip address 192.168.252.4 255.255.255.0
 encap frame
 frame-relay map ip 192.168.252.3 421
 no shut
!

R4, R5 can do ping to R3
R3 can do ping to R4, R5

R3 can do ping to its s1
BUT R3 TIMEOUT WHEN PING ITS S0.

Regards,
Fanglo
