HSRP as everyone knows is the First Hop Redundancy Protocol used primarily for redundancy in networks having two or extra paths from LAN change in the direction of the WAN router.
Utilizing HSRP with a single group just one path stays energetic at a time whereas the opposite stays on standby and solely turns into energetic as soon as the first path fails.
What’s A number of HSRP (MHSRP)
We are able to load share visitors in HSRP through the use of function set known as as A number of HSRP whereby for a selected Group first path will likely be energetic and second as backup and for different group second path with be energetic and first the backup.
In some situations, it turns into important that we make the most of each WAN Hyperlinks paths. MHSRP configuration could be fairly the answer taste of FHRP the place host community to the server community could be configured beneath Multigroup HSRP.
State of affairs Instance: MHSRP
Under diagram will likely be referred to whereas explaining a lab state of affairs of MHSRP –
- For group 1, R1 is the default energetic router based mostly on highest precedence (100) whereas R2 is standby having precedence of 95.
- For group 2, R2 is the default energetic router based mostly on highest precedence (100) whereas R1 is standby having precedence of 95.
- When both of R1 or R2 is down, the opposite router turns into energetic and assumes the Energetic Default Gateway for each the group ie standby 1 and standby 2.
Important to share that Preemption key phrase helps the Router with highest precedence for group to take over when it’s again to up standing and operating.
Configuration:
R1(config-if)#standby 1 precedence 100
R1(config-if)#standby 2 precedence 95
R1(config-if)#standby 1 preempt
R1(config-if)#standby 2 preempt
R1(config-if)#standby 1 ip 192.168.1.1
R1(config-if)#standby 2 ip 192.169.1.2
R1(config-if)#standby 2 precedence 100
R1(config-if)#standby 1 precedence 95
R1(config-if)#standby 1 preempt
R1(config-if)#standby 2 preempt
R1(config-if)#standby 1 ip 192.168.1.1
R1(config-if)#standby 2 ip 192.169.1.2
