Hi guys,

I am learning ECC  design and set up this sample lab to reinforce my concepts:

1)  Is it normal for Virtual gateway address not be pingable from host?   host 100.100.100.100 can ping 100.100.100.1 or 100.100.100.2  but not virtual gateway 100.100.100.200.  I can see ICMP ping request arriving at EX1 for 100.100.100.200 but it ignores it.

2) Normally when all links in particular vlan are down, then  associated irb will also go down.  But I noticed in  ECC design, this is not the case.  For example, on EX2,  I shutdown ge-0/0/2 but irb.100 is still up:

Is it expected behavior?  Is there any knob that I can use to bring irb.100 down if all the interfaces are also down?

Thanks!!

Hi,

Q1: Yes is normal until you add following command:
set interfaces irb unit 100 virtual-gateway-accept-data

Q2: Try following command, it may help:

set protocols evpn no-core-isolation
