. b# ]* }! k2 N- o" j8 H# [! x: MYou can eliminate configurations with the word ‘standby’, as that would be HSRP, not VRRP. Also, I think the options that put things like vrrp group 1 ip x.x.x.x are wrong. You don’t need the word ‘group’ in the configuration line. The number 1 is the group number. Anyway, just take a good look a t a few valid VRRP configuration examples so that you will be able to recognize invalid ones.

Explanation:* j: l$ C; b/ b4 j
+ Access – The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs.
8 U8 s0 c& J8 g9 R0 f+ Default – The default template gives balance to all functions.( G" s) T- l" `+ O, _, |0 v
+ Routing – The routing template maximizes system resources for IPv4 unicast routing, typically required for a router or aggregator in the center of a network.- G2 | }, M0 _4 {9 w- U
+ VLANs – The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 switch.
