VRRPv2 and WS-C3850-12XS

[adeliomoreira]

Hi,

I'm running the version 3.07.04E on switches WS-C3850-12XS, the license level is Ipbase and i would like to use the VRRPv2 on both devices. The commands are not showing up on the interfaces settings. The IP routing is enable and i'm using CDP protocol to share the VLAN id to other lan switches. Why i'm not able to enable this protocol VRRPv2, on these switches, since it was introduced on IOS-XE 2.1 version?(HSRP is  not a option for this case) 

Best regards,

Adelio Moreira

Hi

I don't even have it on 3850 with advanced ipservices so I doubt you have it on ipbase , I only have hsrp no gblp either or vrrp

Hi

yes I understand but its not in the syntax in ios-xe which would definitely suggest it hasn't been added , I don't see in the configuration guides for 3.7.4 or release notes only hsrp which is specific to your release , same with 3.6.4 , just because a previous doc says its available always check your current release/config guides to be sure , there below

Cisco TAC should be able to tell you why exactly its not there

Hi everyone,

I ran into the same problem that only HSRP and GLBP are available on a 3850-48XS-S switch running v16.6.4. It couldn't enable VRRP on VLAN or physical interfaces.

I checked the docs and only found references to VRRPv3.

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipapp_fhrp/configuration/xe-3e/fhp-xe-3e-book/VRRPv3-Protocol-Support.html

I did what the guide mentioned and enabled v3 and all of a sudden, the "vrrp" command was available on the VLAN interface

Below is what I tried:

3850-48XS-S(config)#int vlan 199
3850-48XS-S(config-if)#ip add 10.0.199.1 255.255.255.0
3850-48XS-S(config-if)#int ten1/0/24
3850-48XS-S(config-if)#no switchport
3850-48XS-S(config-if)#ip add 10.0.0.1 255.255.255.0
3850-48XS-S(config-if)#vrr?
% Unrecognized command
3850-48XS-S(config-if)#vrrp 1 pri 20

3850-48XS-S(config-if)#default int ten1/0/24

3850-48XS-S(config)#fhr
3850-48XS-S(config)#fhrp ?

  version      Configure which FHRP version is allowed to run

3850-48XS-S(config)#fhrp version vr
3850-48XS-S(config)#fhrp version vrrp ?

3850-48XS-S(config-if)#vrrp ?

3850-48XS-S(config-if)#exit
3850-48XS-S(config)#fhrp version vrrp  ?
  v3  Unified VRRP - VRRPv3 for IPv4 and IPv6

3850-48XS-S(config)#fhrp version vrrp v3

3850-48XS-S(config)#int vlan 199
3850-48XS-S(config-if)#vrr
3850-48XS-S(config-if)#vrr
3850-48XS-S(config-if)#vrr
3850-48XS-S(config-if)#vrr?
% Unrecognized command
3850-48XS-S(config-if)#exit

And in the VRRP sub-config mode you can enable VRRPv2 compatibility.

interface Vlan199
 ip address 10.0.199.1 255.255.255.0
 vrrp 199 address-family ipv4
  vrrpv2
  address 10.0.199.1 primary
  exit-vrrp

!
