i ahve 2 core 6509 switches and i am doing hsrp between them.core 1 is connected to firewall1 and core 2 connected to firewall 2.both core swicthes are connected via trunk link. in this case i am gving ip to physical interface and doing hsrp.problem is firewll is Juniper and they do NSRP in which they one firewall is active and other firewall is inactive.i am using /29 subnet for the hsrp in which core1 has 10.1.1.1/29 , core 2 has 10.1.1.2/29 hsrp is 10.1.1.3 and firewall NSRP ip is 10.1.1.4.
now problem is both cores can not communicate with each other and remain master.
core 1 shows ip route for 10.1.1.2 towards firewall and core2 has route for 10.1.1.1 towards firewall2 so they cannot communicate remain master.
tried configuring L3 link between core switches and added static route for connectivity between 2 switches.now core1 can communicate with core2 ip but HSRP is not changing and remain master in both switches..
