Can you send the output of a "show ip route", "show ip int brief", and a
"show frame map" from both routers? Also can you "debug ip icmp" on R3
and then ping to see if the pings are arriving from R5 but not making it
back?

Subject: Frame Relay Issues (IE WB vol 1 version 3.00 LAB 5)
Hello GS,
Can someone tell me what could cause packet loss on just one DLCI? I'm
currently working in LAB 5 in the IE workbook, and my connection from R3
to
R5 is flaking out on me. These two routers have DLCI's mapped to other
routers and I'm not seeing any packet loss on these connection. So that
leads me to believe there isn't a physical problem here. The setup is
the
following, R3 maps to R5 via DLCI 305 and R5 maps to R3 via 503.
Config for R3
interface Serial0/0
ip address 162.1.0.3 255.255.255.0
encapsulation frame-relay
clock rate 2000000
frame-relay map ip 162.1.0.2 302 broadcast
frame-relay map ip 162.1.0.4 304 broadcast
frame-relay map ip 162.1.0.5 305 broadcast
no frame-relay inverse-arp
Config for R5
interface Serial0/0
ip address 162.1.0.5 255.255.255.0
encapsulation frame-relay
frame-relay map ip 162.1.0.2 504
frame-relay map ip 162.1.0.3 503 broadcast
frame-relay map ip 162.1.0.4 504 broadcast
no frame-relay inverse-arp
Here's what I'm seeing when I try to ping across the link.
Rack1R5#ping 162.1.0.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 162.1.0.3, timeout is 2 seconds:
.!.!.
Success rate is 40 percent (2/5), round-trip min/avg/max = 28/28/28 ms
Rack1R5#ping 162.1.0.4 <------- pings look good to R4 on DLCI 504
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 162.1.0.4 , timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/31/32 ms
Thanks,
Duane
