Currently, I have a problem tracking down the serial when the HSRP of interface 10.20.6.48 is down. The routes of a particular network is keep on going to the router1 when the router1 interface is down.
How can I do it as I am using GLBP on the other end. The network diagram as attached..
do you mean to say the HSRP LAN links fail and the traffic still gets routed over the serial link.
If this is the case then you have to run a routing protocol
I am running ospf on all 4 routers..What are the things that I need to take care if I am using routing protocol of OSPF? any specified configuration for me on OSPF for this problem?
Narayan, yup, you are right. When HSRP LAN for the router1 failed, it still get routed for one particular network to the serial and the tracert will keep on boucing back in between the 2 serial links.
Thanks, hope to hear from you all again.
it seems your configs are showing something else than the original picture (IP addresses seem to be swapped between particular routers).
Generally, I'd check the passive-interface FastEthernet0/0 commands, they might make your routing table confused when the FastEthernet0/0 goes down.
Thanks a alot.I might accidentally changed it wrongly when want to mask the real ip address out.
Anyway, can i know what is the rectification on the passive-interfae Fa0/0 commands and how to go about it?
Basically now if my HSRP active router1 down, the network won;t be able to go through to Router3.
I also noticed there is GLBP configured on one int only, using 188.8.131.52 as a virtual address, while the same address used as an int address on other router - strange.
Also that static route redistribution into OSPF might make it confused when the interface goes down.
The config looks OK now.
Could you please once more describe the problem with more details?
Which int. goes down, what subnet is routed incorrectly, which direction (i.e., is the traffic leaving the site incorrectly or coming to the site via wrong router)?
