We have 2 Cisco 1921, as R1 and R2 connected to 2 Cisco2960G SW1 and SW2
Cisco 2960G are connected to each other using a Trunk interface.
Main point to point link is connected to SW1 and redundant hand off of same point to point link is connected to SW2. At one point of time, only one point to point link will be active. Redundant hand off will become active in case main link does down.
R1--SW1--P2P1
|
R2--SW2--P2P1 (redundant handoff)
Generally, we configure the point to point link as /30 (255.255.255.252) subnet.
But if I have to configure HSRP between R1 and R2 then I can not configure /30. Will it work if I configure /29 on the point to point link.
R1 Config:
interface GigabitEthernet0/0.3
encapsulation dot1Q 3
ip address 10.0.0.3 255.255.255.248
standby 1 priority 105
standby 1 ip 10.0.0.2
standby 1 preempt delay minimum 60
R2 Config:
interface GigabitEthernet0/0.3
encapsulation dot1Q 3
ip address 10.0.0.4 255.255.255.248
standby 1 priority 100
standby 1 ip 10.0.0.2
Remote Router On the Other End Of The P2P Circuit:
interface GigabitEthernet0/0.3
encapsulation dot1Q 3
ip address 10.0.0.1 255.255.255.248
