Hi Tony, Do both interfaces on the hub need to be point to point (ie does the lab explicitly tell you to use point-to-point)? I think you should have one multipoint interface at the hub router with two frame maps pointing to each remote router's IPs.
I dont have the lab book with me so I cant check what the scenario is. HTH Matt CCSI #31207 On 23/01/07, Tony Hidalgo <[EMAIL PROTECTED]> wrote:
Hello people from the list. I have a question regarding the typical hub and spoke fram relay configuration. In the Lab that I am currently working on, it was required to configure the HUB router with one PHYSICAL and two LOGICAL (Point to Point) frame-relay links on the Same interface. In other words, there is S0/0-> R3, S0/0.2->R2 and S0/0.4->R4. Now, the catch is that both subinterfaces MUST belong to the same ip subnet. I was able to configure all ip's, pvc's, etc but I noticed that for some reason, either of the spokes cannot ping the HUB even though the FR PVC is up and even OSPF adjacencies are being created between the routers. Also, both spoke routers can ping each other (going through the HUB). So my question is: Why can't I ping from either spoke routers to the HUB but I CAN ping between the spokes and OSPF adjecencies are being formed between the Spokes and Hub? Is there a problem with ICMP protocol in this setting? Can anybody point me to the right direction? The relevant config is pasted below: >From one Spoke- interface Serial0/0 ip address 172.16.124.4 255.255.255.0 encapsulation frame-relay no fair-queue frame-relay map ip 172.16.124.1 401 broadcast frame-relay map ip 172.16.124.5 401 no frame-relay inverse-arp >From the other Spoke- interface Serial0/0 ip address 172.16.124.5 255.255.255.0 encapsulation frame-relay IETF ip ospf priority 0 frame-relay map ip 172.16.124.2 201 broadcast frame-relay map ip 172.16.124.4 201 no frame-relay inverse-arp frame-relay lmi-type cisco >From the HUB- interface Serial0/0 ip address 172.16.13.1 255.255.255.0 encapsulation frame-relay IETF frame-relay map ip 172.16.13.3 103 broadcast no frame-relay inverse-arp frame-relay lmi-type cisco ! interface Serial0/0.2 point-to-point ip address 172.16.124.2 255.255.255.0 ip ospf network point-to-multipoint frame-relay interface-dlci 102 ! interface Serial0/0.4 point-to-point ip address 172.16.124.1 255.255.255.0 ip ospf network point-to-multipoint frame-relay interface-dlci 104 Thanks in advanced ____________________________________________________________________________________ Have a burning question?
