Hi everyone

Below link lists various scenarious showing " VC SPLIT CONDITION"

 

https://kb.juniper.net/InfoCenter/index?page=content&id=KB19732&cat=EX4200_1&actp=LIST

 

1)How   long Master RE switch wait if it can not see BACKUP RE,  before declaring SPLIT Condition and declares itself as Line card?

###############

Consider the following: 

MASTER RE ( SW1)VCP0---- VCP0-BACKUP RE(SW2)VCP1--VCP1SW3 ( Linecard)

 

 

Let say  VCP0 on MASTER RE goes down, will MASTER RE rightaway declare itself as line card or will it still wait for " Timer" to expire and then decalre itslef as " LINE CARD" ?

Have a nice weekend!!

Good day,

 

If VCP0 goes down SW1 will detect that it connected to smaller part of VC (1 switch instead 2).

For redunduncy, you need to have at least two connections to different switches.

 

This document explains all other details related to the VC.
