4.6 OSPF

I matched the solution exactly, yet no load balancing going on here. So, for a stab in the dark, i set the maximum-paths at 4 to make sure the default effect will happen. Both the serial and ethernet interfaces have the same bandwidth value. any ideas here?

  • Same happening with me as well....

     

    r5#sh int se 0/0 | i BW
      MTU 1500 bytes, BW 10000 Kbit, DLY 20000 usec,

    r5#show  interfaces ether0/0 | i BW
      MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,

    do we need to do somthing esle as well apart from changing bandwidth even i tried cleraking ospf session on both rtr ??

  • If you shut your ethernet, where does the traffic go, and what does your metric look like? Is it the same as what you currently show over the Ethernet?

     

    It worked fine for me when simply configuring the bandwidth, so no configuration extras should be needed.

  • Maybe if you paste the sh ip ospf interface brief will be useful:

    Here my output and load balancing work well

  • hi saurabh244,

    this might sound silly, but verify that your frame relay interface is in fact included and advertised into ospf using sh ip ospf inter s0/0 (your frame intf). do you see your ospf neighbors? that is the first verification. i might be out of line here and it could be something else, but thought i'd mention the obvious. sorry.
