hi group
which vrrp implementaion is most "ccie style"?

1. use interface ip of master router as vrrp address -> tracking not possible

          R1--FR
          | \
Client-ETH| R3--->
          | /
          R2--FR

R1: interface FastEthernet0/0
    ip address 125.1.125.1 255.255.255.0
    vrrp 1 ip 151.1.125.1

R2: interface FastEthernet0/0
    ip address 125.1.125.2 255.255.255.0
    vrrp 1 ip 125.1.125.1

2. use extra address (equivalent to hsrp) and track (if redundant uplinks)?

R1: track 1 interface serial 0/0/0 line-protocol

    interface FastEthernet0/0
    ip address 125.1.125.1 255.255.255.0
    vrrp 1 ip 125.1.125.3
    vrrp 1 track 1 decrement 20
    vrrp 1 priority 110

R2: track 1 interface serial 0/0/0 line-protocol

    interface FastEthernet0/0
    ip address 125.1.125.2 255.255.255.0
    vrrp 1 ip 125.1.125.3
    vrrp 1 track 1 decrement 20
    vrrp 1 priority 100
