Having problems with lab 8. Basically I can bring up
the two routers connected via point-to-point frame
relay. However, I can not bring up the multipoint
connection from r5 to r2 and r3. Can anyone spot the
issues or at least explain what a looped serial
interface could imply? Here are my interfaces on the
fr switch:
interface Serial0 (goes to r2)
no ip address
no ip directed-broadcast
encapsulation frame-relay
no ip mroute-cache
no keepalive
no fair-queue
frame-relay route 105 interface Serial2 501
interface Serial3 (goes to r3)
no ip address
no ip directed-broadcast
encapsulation frame-relay
keepalive 20
cdp enable
frame-relay lmi-type ansi
frame-relay route 305 interface Serial2 503
R3 serial int s1
interface Serial1
ip address 137.20.100.35 255.255.255.224
encapsulation frame-relay
ip ospf network point-to-multipoint
clockrate 64000
cdp enable
frame-relay map ip 137.20.100.34 305 broadcast
frame-relay lmi-type ansi
****** shows as up, down (looped)
R2 int s0
interface Serial0
ip address 137.20.100.33 255.255.255.224
encapsulation frame-relay
no fair-queue
clockrate 64000
frame-relay map ip 137.20.100.34 105 broadcast
frame-relay lmi-type ansi
***** shows in show int as up, down*******
R5 subinterfaces
interface Serial1
no ip address
encapsulation frame-relay
bandwidth 2000
keepalive 15
no fair-queue
frame-relay lmi-type ansi
!
interface Serial1.1 multipoint
ip address 137.20.100.34 255.255.255.224
frame-relay map ip 137.20.100.33 501 broadcast
frame-relay map ip 137.20.100.35 503 broadcast
!
interface Serial1.2 point-to-point
ip address 137.20.200.17 255.255.255.240
frame-relay interface-dlci 504
!
***** again point-to-point works fine, but not multi***
