Hi everyone!
We have a EX8208 VC in full mesh (two EX8208 witch dual SRE320, and two XRE200) at the core layer and a EX6208 at the access layer (with a LAG).
We have configured these commands in order to have high avalibility on routing engines:
set system commit synchronize
set chassis redundancy graceful-switchover
set routing-options nonstop-routing
In order to test our availability, we have PCs on both sides (core and acces layer) running a ping between them and making a telnet session to the remote switch.
Our tests are:
- We remove a link of the LAG = it works fine! (good).
- We remove from the chassis one SRE320 (EX8208) or SRE64-4XS (EX8208) (which is in master role) = We can see that 5 to 7 pings are lost, and the telnet session is broken (bad ofr us). Ping responds again and we can make a new telnet session.
- We swithover from master to backup routing engine with "request chassis routing-engine master switch" command = We see the same result... lost of pings and telnet session. We can recover connections after 5 secs more less.
Does we need another command to don't loss connections?
Regards!
