3.8.2 VRRP

The following table describes the capacity limits for VRRP.

Table 3-42 VRRP Capacity Limits
Model	Maximum number of virtual routers		With the failure monitoring interface Max VRRP polls
Model	Per interface	Per switch	Per virtual router	Per switch
All models	255^#1	255^#1	16^#2	255^#2

#1: Total IPv4 and IPv6 virtual routers

#2: Sum of fault-monitoring interfaces and VRRP pollings

Table 3-43 VRRP capacity limits (when the group-switching facility is used)
Model	Maximum number of virtual routers		Maximum number of groups	Maximum number of follower virtual routers per group	Maximum number of fault monitoring interfaces and VRRP polling instances
Model	Per interface	Per switch	Maximum number of groups	Maximum number of follower virtual routers per group	Per virtual router	Per switch
All models	255^#1	1023^#1	255	1022	16^#2	255^#2

Note #1: A IPv4/IPv6 can have up to 255 virtual routers. However, a maximum of 1023 virtual routers can be operated by creating a follower virtual router using the group switching function.
Note #2: The sum of fault monitoring interfaces and VRRP polling.
