Creating Interface Parameters
You can configure up to 4 virtual routers IDs on an IP interface. Each virtual router instance
can manage up to 16 backup IP addresses, including up to 16 secondary IP addresses. If you
have multiple subnets configured on an Ethernet interface, you can configure VRRP on each
subnet.
To configure an interface:
CLI Syntax: config>router
interface ip-int-name
address ip-addr{/mask-length|mask} [broadcast {all-
ones|host-ones}]
secondary {[ip-addr/mask|ip-addr][netmask]}
[broadcast {all-ones|host-ones}][igp-inhibit]
Example : config>router> interface “ethel”
config>router>if$ address 10.10.14.1/24
config>router>if# secondary 10.10.16.1/24
config>router>if# secondary 10.10.17.1/24
config>router>if# secondary 10.10.18.1/24
config>router>if# exit
The following example displays the IP interface configuration:
A:SR1>config>router# info
#------------------------------------------
echo "IP Configuration "
#------------------------------------------
interface "system"
address 10.10.0.1/32
exit
interface "fred"
address 123.123.123.123/24
exit
interface "ethel"
address 10.10.14.1/24
secondary 10.10.16.1/24
secondary 10.10.17.1/24
secondary 10.10.18.1/24
exit
router-id 10.10.0.1

A:SR1>config>router#
