Adding a Redundant Core - Dumb Question

troy_alan — Wed, 26 Jun 2019 00:54:52 GMT

Setting up a second BlackDiamond 8810 as a active-active redundant core. There are 41 vlans with Gateway addresses, do I have to setup VRRP for all 41? Is there a best practice for the number of VRRP in use? Is there a easy way to create this without doing it one at a time?

Hi Roy,

VRRP is a functionality to serve default gateway redundancy for certain subnet, ie. certain VLAN.
You can find limits for VRRP scaling (number of VRIDs, VRRP instances per switch) in the release notes: https://documentation.extremenetworks.com/release_notes/ExtremeXOS/30.2/downloads/GUID-239F0B67-21C6-4460-88BE-99289275F8C1.pdf

Hope that helps,
Tomasz
