default gateway failover

[Tyrone at telecity.se]

Hi,

 

I'm trying to do default gateway failover for a single VLAN interface
connected to 2 switches and two freebsd 5.4 routers.

I have BGP running on both routers.

The webserver is configured with 192.168.1.12 and a GW address of
192.168.1.10 which is the virtual router address in case the default
gateway goes down it will take another route supplied by 802.1d
spanning-tree and CARP.

The drawing is at the bottom of this mail

Any one get a solution like this working or maybe you see something that
is wrong?

 

Here is my config

 

Router1#vlan403:
flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500

        inet 192.168.1.9 netmask 0xfffffff8 broadcast 192.168.1.15

        ether 00:30:48:88:21:f3

        media: Ethernet autoselect (1000baseTX <full-duplex>)

        status: active

        vlan: 403 parent interface: bge1

 

Router1#ifconfig carp403 create

Router1#ifconfig carp403 vhid 1 pass love 192.168.1.10/29

 

Router1#carp403: flags=41<UP,RUNNING> mtu 1500

        inet 192.168.1.10 netmask 0xfffffff8

        carp: MASTER vhid 1 advbase 1 advskew 0

 

Router2#vlan403:
flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500

        inet 192.168.1.11 netmask 0xfffffff8 broadcast 192.168.1.15

        ether 00:30:48:85:1a:8e

        media: Ethernet autoselect (100baseTX <full-duplex>)

        status: active

        vlan: 403 parent interface: bge0

 

Router2#ifconfig carp403 create

Router2#ifconfig carp403 vhid 1 advskew 100 pass love 192.168.1.10/29

 

Router2#carp403: flags=41<UP,RUNNING> mtu 1500

        inet 192.168.1.10 netmask 0xfffffff8

        carp: BACKUP vhid 1 advbase 1 advskew 100

 

The webserver is configured with 192.168.1.12 and a GW address of
192.168.1.10 which is the virtual router address in case the default
gateway goes down it will take another route supplied by 802.1d
spanning-tree.
