HSRP or VRRP Configuration

[Dipesh Patel]

DEar all,

Can you suggest the configuration for for router LAN intweface for the  topology attached :

Case: 1 - HSRP configuration

Case - 2 VRRP cofnngiruation

Topology:

Hello Dipesh,

from the network diagram if the devices that connect to the multilayer switches via the L2 LAN switch are routers I would use a routing protocol instead of HSRP or VRRP with a preference for OSPF.

HSRP and VRRP are well suited to provide a resilient default gateway to end user systems.

A possible use of HSRP/VRRP to provide a fault tolerant next-hop when static routes are used is possible so if the routers in the bottom of your picture are not under your control and you want to use static routes you can use HSRP or VRRP on the two multilayer switches on the top.

SW1:

interface vlan xx

ip address a.b.c.253/24

standby 1 address a.b.c.254

standby 1 priority 105

standby 1 preeempt

standby 1 track

SW2:

interface vlan xx

ip address a.b.c.252/24

standby 1 address a.b.c.254

standby 1 priority 100

standby 1 preeempt

Hope to help

Dear Giuseppe,

Sorry , Qoe correcton is there. In my  topology , only one CORE switch (L3) is there.

And Require to select the one of the router to push data out side. from LAN.

And also the reverse path that is Router to LAN.

Hi,

You are not so clear.

First of all you need at least L3 switches / routers to do HSRP or VRRP.
With your single L3 switch you canot configure any redundancy protocols like HSRP.

But I hope you have two routers, so you can configure HSRP between them so that the one active router only will send the traffic to outside from LAN.

Please rate the helpfull posts.

hi,

further adding to the above remarks, if you're running Cisco only devices on this setup, then go for HSRP as it is considered a proprietary redundancy protocol. VRRP is an industry standard used when using mutlivendor devices.
