VRRP / track-interface - Can't use BondEthernet

mmercier

Hello,

I am playing with TNSR on baremetal in a lab environment, attempting to configure VRRP. The basic setup is as follows:

Two servers with the following NICs:
Intel i350 4 port 1Gpbs - WAN
Intel i710 2 port 10Gpbs - LAN

On the LAN side I have a MLAG/vPC switch pair configured, with the two interfaces on the i710 card members of a bond interface, with one port to each switch.

interface bond 0
    mode lacp
    load-balance l34
exit

interface TenGigabitEthernet2/0/0
    bond 0
exit
interface TenGigabitEthernet2/0/1
    bond 0
exit

I am attempting to configure VRRP on the WAN interface, with the following currently configured.

interface GigabitEthernet1/0/0
    ip vrrp-virtual-router 1
        preempt true
        priority 255
        accept-mode false
        v3-advertisement-interval 100
        virtual-address 10.254.2.41
    exit

The example for VRRP shows to track the LAN side interface for the WAN, see - Virtual Router Redundancy Protocol

When attempting to add the track-interface, I see the following:

rtrexllab01 tnsr(config-vrrp4)# track-interface
  GigabitEthernet1/0/0
  TenGigabitEthernet2/0/0
  TenGigabitEthernet2/0/1

The idea behind the setup is that one of the switches can become unavailable, with traffic continuing to flow via the still active switch.

Is it not possible to use a BondEthernet as the track-interface? Would this be a feature request? Are end users able to see the feature request list?

Thanks,
Mike

I am able to use track-interface with VRRP, but have run into a separate issue - see BondEthernet interfaces don't get status from slave(s)

I'll update here if/when I get a resolution to that issue.

Thanks,

Hello,

Something I should have included in the original message.

rtrexllab01 tnsr# show version

Version: 22.10-2
Build timestamp: Tue Nov  1 18:41:40 2022 UTC

This TNSR instance is not configured for package updates.

For information see 'show documentation'

Thanks,
Mike

My specific issue came down to the fact that the BondInterface needs to be enabled before it can be used as a track-interface.

e.g.

interface bond 1
    mode lacp
    load-balance l34
exit

NOTE: interface BondEthernet1 is not enable.

When trying to add the track-interface

rtrexllab01 tnsr(config)# interface GigabitEthernet1/0/0
rtrexllab01 tnsr(config-interface)# ip vrrp-virtual-router 1
rtrexllab01 tnsr(config-vrrp4)# tr
 BondEthernet0              BondEthernet0.610          GigabitEthernet1/0/0       GigabitEthernet1/0/1
 TenGigabitEthernet2/0/0    TenGigabitEthernet2/0/1
rtrexllab01 tnsr(config-vrrp4)# track-interface

As seen above, the BondInterface1 is not available.

rtrexllab01 tnsr(config)# interface BondEthernet1
rtrexllab01 tnsr(config-interface)# enable
rtrexllab01 tnsr(config-interface)# exit
rtrexllab01 tnsr(config)# interface GigabitEthernet1/0/0
rtrexllab01 tnsr(config-interface)# ip vrrp-virtual-router 1
rtrexllab01 tnsr(config-vrrp4)# tr
 BondEthernet0              BondEthernet0.610          BondEthernet1              GigabitEthernet1/0/0
 GigabitEthernet1/0/1       TenGigabitEthernet2/0/0    TenGigabitEthernet2/0/1
rtrexllab01 tnsr(config-vrrp4)# track-interface

BondEthernet1 is not available to use as a track-interface.

Thanks,
Mike
