vsx-sync dhcp-relay

Description

Enables VSX synchronization of DHCPv4 and DHCPv6 relay configurations on the primary VSX node to the secondary peer.

The no form of the command disables the VSX synchronization of DHCPv4 and DHCPv6 relay configurations to the secondary peer; however, it does not remove the existing DHCPv4 and DHCPv6 relay configurations from the secondary VSX peer.

Command context

Examples

This example enables VSX synchronization for DHCPv4 relay configurations. The first six lines in the example show DHCPv4 relay configurations. The last two lines show how to enable VSX synchronization for the DHCP relay configurations:

switch(config)# interface 1/1/1
switch(config-if)# ip helper-address 192.168.10.1
switch(config-if)# ip helper-address 192.168.20.1
switch(config)# interface 1/1/2
switch(config-if)# ip helper-address 192.168.30.1
switch(config)# dhcp-relay option 82
switch(config)# vsx
switch(config-vsx)# vsx-sync dhcp-relay

This example enables VSX synchronization for DHCPv6 relay configurations. The first seven lines in the example show DHCPv6 relay configurations. The last two lines show how to enable VSX synchronization for the DHCP relay configurations:

switch(config)# dhcpv6-relay
switch(config)# interface 1/1/1
switch(config-if)# ipv6 helper-address unicast 2001:db8:0:1::
switch(config-if)# ipv6 helper-address multicast FF01::1:1000 egress 1/1/2
switch(config)# interface 1/1/2
switch(config-if)# ipv6 helper-address unicast 2001:db8:0:2::
switch(config)# dhcpv6-relay option 79
switch(config)# vsx
switch(config-vsx)# vsx-sync dhcp-relay

Disabling VSX synchronization for DHCP relay configurations:

switch(config)# vsx
switch(config-vsx)# no vsx-sync dhcp-relay
