Enabling the v2 checksum computation method in a VRRPv3 IPv4
session
Conguring an alternate VRRPv2-style checksum in a VRRPv3 IPv4 session for compatibility with third-party network devices.
VRRPv3 uses the v3 checksum computation method by default for both IPv4 and IPv6 sessions on Brocade devices. Third-party
devices may only have a VRRPv2-style checksum computation available for a VRRPv3 IPv4 session. The use-v2-checksum
command is entered in interface conguration mode.
1. Use the congure command to enter global conguration mode.
device# configure
2. To enable VRRP globally enter the router vrrp command.
device(config)# router vrrp
3. Enter the interface command with an interface type and number.
device(config)# interface ethernet 1/2/4
4. To congure a VRRP virtual routing ID use the ip vrrp vrid command with an associated ID number.
device(config-if-e10000-1/2/4)# ip vrrp vrid 14
5. To enable VRRP version 3 (VRRPv3) enter the version command with version number of v3.
device(config-if-e10000-1/2/4-vrid-14)# version v3
6. To enable v2 checksum computation method in an IPv4 VRRPv3 session, use the use-v2-checksum command in the VRRP
conguration mode.
device(config-if-e10000-1/2/4-vrid-14)# use-v2-checksum
7. Enter the IP address for the interface using the ip-address command.
device(config-if-e10000-1/2/4-vrid-14)# ip-address 10.14.14.99
8. To activate the interface, enter the activate command.
device(config-if-e10000-1/2/4-vrid-14)# activate
The following example shows the v2 checksum computation method enabled for an VRRPv3 IPv4 session on a Brocade device.
device# config
device(config)# router vrrp
device(config)# ethernet 1/2/4
device(config-if-e10000-1/2/4)# ip vrrp vrid 14
device(config-if-e10000-1/2/4-vrid-14)# version v3
device(config-if-e10000-1/2/4-vrid-14)# use-v2-checksum
device(config-if-e10000-1/2/4-vrid-14)# ip-address 10.14.14.99
device(config-if-e10000-1/2/4-vrid-14)# activate
Enabling accept mode in VRRP non-Owner Master router
To
congure a non-Owner Master router to respond to ping, traceroute, and Telnet packets destined for the virtual IPv4 or IPv6
address of a VRRP cluster, use the accept-mode command in the VRRP conguration mode.
