Gorup,
I have no explanation for the following behavior:
lo0 4.4.4.4/32
R4 ---- dlci 405 -------- fr ------ dlci
504---- R5
f0/0 155.1.146.4/24
R5 has no route to R4 lo0 nor to R4 f0/0. Instead it has frame-relay static
mapping for these 2 destination.
Understandably R5 can NOT ping R4 lo0
what I can NOT understand is how does it manage to ping R4 f0/0
<<<<<<<<< R5
interface Serial0/0
ip address 155.1.0.5 255.255.255.0
encapsulation frame-relay
no fair-queue
clock rate 128000
frame-relay map ip 4.4.4.4 504 broadcast
frame-relay map ip 155.1.0.4 504 broadcast
frame-relay map ip 155.1.146.4 504 broadcast
no frame-relay inverse-arp
end
R5#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
Gateway of last resort is not set
155.1.0.0/24 is subnetted, 1 subnets
C 155.1.0.0 is directly connected, Serial0/0
5.0.0.0/32 is subnetted, 1 subnets
C 5.5.5.5 is directly connected, Loopback0
R5#show frame-relay map

R5#ping 155.1.146.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 155.1.146.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/31/32 ms
