Hi

My problem is my router B is the backup of router A , and in case od failure of router A how my firewall will come to know that it has to go to router B as in my ospf routes on my firewall i can only see OSPF routes publish form router A and in the neighbour details of my firewall i can see both the routers but with Full state it should be one Full and one DR/Full.

Important thing is that Router A is now active for my HSRP may be thats trhe reason I am getting routes only from Router A.

Please Clearify

You will always see both neighbors up and see both routes in the OSPF database. You no longer need the HSRP and will many times cause you issues if you attempt to run both a routing protocol and hsrp.

What you want to do is to manipulate the ospf metrics so that only the route to router A is placed into the firewall routing table. If it were to lose the route from router A it would then select the route it learned from router B.

How you do this will depend on what type of ospf routes these are. In general you can set ospf costs when you redistribute, on interfaces and with distribution lists.

Hello Asfar,

there is no dependency of OSPF on HSRP they are different separate protocols

DR/Full

Are you sure that your firewall isn't the OSPF DR in your setup ?

Hope to help

As mentioned befor as long as you have OSPF neighbor adjacencies to the two rtrs (active,standby) you should be fine

HSRP

RTRA - Active

HSRP Prioirity

RTRB = Standby

Hsrp Priority =

OSPF should have no problems if the dajacencied are formed from th VIP perspective

meanins as lons as OSPF can reach the physical interfaces routers (active,standby) everyting is cool.

OSPF --> Route in table fpor active routers

OSPF--> In the event the active rtr goesd down Multicast packets are sent between the two devices every 5sec*3 then the obviouslly the standcy rtr accts as the active and the routes is in the table

Active/Standby does not matter.

OSPF --> Route in table for active routers

-----

No route in table based on best metric

OSPF--> In the event the active rtr goesd down Multicast packets are sent between the two devices every 5sec*3 then the obviouslly the standcy rtr accts as the active and the routes is in the table

No, route in table based on best metric, if router with best metric goes down FW will choose the other routers routes.

Who makes the FW? Does it support equal-cost multipath? If so and rtr-A and rtr-B have access to same networks then it should install both routes in routing table.

Hi

I am attaching the configuration of my Routers can you please check whats wrong as I am still not clear whats the problem
