Hi All,

 

Recently, i have initiated a software upgrade activity through Cloud Vision Portal. Following was the staging procedure on a cabinet – in which we have two Switches in MLAG peer.

 

Staging Procedure :

 

  1. Pre Configuration Snapshot
  2. Checking MLAG Health
  3. Entering BGP Maintenance
  4. Upgrade the EOS
  5. Existing BGP Maintenance
  6. Post Configuration Snapshot

First Stage of Pre Configuration Snapshot is successful.

For the second stage to be successful, i had to re configure the reload delay under MLAG from 60 – 300. With value of 60, Stage is failing.

Stage 3 is also successful , where in my Switch enters in to the Maintenance mode.

Stage 4 is also successful, where in Switch gets loaded with the required version of EOS and reboots happens and Switch turns back On.

Real issue is with Stage 4 in which we get all below mentioned logs :

“Checking BGP convergence of all VRFs every 30s, attempt 1, error: BGP doesn’t converge on VRFs: map[default:BGP convergence state is: Timeout reached. Pending Peers is not 0: 5]â€

After this log,

Exit BGP Maint
Timeout in 11m0s…

Exit BGP Maint
Checking BGP convergence of all VRFs every 30s, attempt 2, error: BGP doesn’t converge on VRFs: map[default:BGP convergence state is: Timeout reached. Pending Peers is not 0: 5]

Exit BGP Maint
Timeout in 10m0s…

Exit BGP Maint
Checking BGP convergence of all VRFs every 30s, attempt 3, error: BGP doesn’t converge on VRFs: map[default:BGP convergence state is: Timeout reached. Pending Peers is not 0: 5]

Exit BGP Maint
Timeout in 8m0s…

Exit BGP Maint
Timeout in 0s…

Exit BGP Maint
Action exitbgpmaintmode on device DC1-B7LEAF-SW01 completed with error: Pre-healthcheck failed: timeout: BGP doesn’t converge on VRFs: map[default:BGP convergence state is: Timeout reached. Pending Peers is not 0: 5]

Exit BGP Maint
Action exitbgpmaintmode completed with error Error executing stage ZHUBUjsAj : Pre-healthcheck failed: timeout: BGP doesn’t converge on VRFs: map[default:BGP convergence state is: Timeout reached. Pending Peers is not 0: 5]

 

Our Switch Model is as follows :

 

Arista DCS-7160-32CQ-F

Current Software version is 4.25.4M

 

Any help/info sharing would be appreciated.
