Configure Accept-mode

Configure accept-mode to be able to respond to ping, traceroute, and telnet commands destined for virtual IPv4 and IPv6 address of VRRP.

1. Shut down the VLAN interface on current master (ES1-24p-1).

   The ES1-24p-2 switch, which is now the backup becomes the master.

   ES1-24p-1 SEFOS# configure terminal 
   ES1-24p-1 SEFOS(config)# interface vlan 100
   ES1-24p-1 SEFOS(config-if)# shutdown 
   ES1-24p-1 SEFOS(config-if)# end
    
   ES1-24p-2 SEFOS# show vrrp
    
   P indicates configured to preempt
    
   Interface vrID Prio P State  Master Address            VRouter Address          
    
   --------- ---- ---- - -----  ------------------------- -------------------------
    
   vlan100   1    150  P Master 192.168.100.10            192.168.100.1            
    
   vlan100   1    150  P Master fe80::210:e0ff:fe2a:fd41  fe80::210:e0ff:fe2c:fd21 
    
    
   ES1-24p-1 SEFOS# show vrrp
    
   P indicates configured to preempt
    
   Interface vrID Prio P State  Master Address            VRouter Address          
    
   --------- ---- ---- - -----  ------------------------- -------------------------
    
   vlan100   1    200  P Init   -                         192.168.100.1            
    
   vlan100   1    200  P Init   -                         fe80::210:e0ff:fe2c:fd21 
   

2. Ping from Host-2 to virtual IPv4 and IPv6 address of VRRP, the ping fails.

   Host-2# ping 1000::5
   Host-2# ping 192.168.100.1
   

3. Enable accept-mode on vlan 100 interface of ES1-24p-2.

   ES1-24p-2 SEFOS# configure terminal
   ES1-24p-2 SEFOS(config)# router vrrp
   ES1-24p-2 SEFOS(config-vrrp)# vrrp version v3
   ES1-24p-2 SEFOS(config-vrrp)# interface vlan 100
   ES1-24p-2 SEFOS(config-vrrp-if)# vrrp 1 ipv4 accept-mode enable
   ES1-24p-2 SEFOS(config-vrrp-if)# vrrp 1 ipv6 accept-mode enable
   ES1-24p-2 SEFOS(config-vrrp-if)# end
   

4. Repeat step 2, the ping will be successful.
