I am learning the different evpn route table, I have a question about __default_evpn__.evpn.0. I came across the following from
here:
__default_evpn__.evpn.0: used for carrying MP-BGP information about ethernet segment routes. This is only applicable for PE that have non default ESI [ie, multihomed CE]. All EVPN NLRI Type 4 routes are also stored in the secondary __default_evpn__.evpn.0 table since they do not contain a Route Target community that corresponds to any specific EVI.
__default_evpn__.evpn.0: 3 destinations, 3 routes (3 active, 0 holddown, 0 hidden)

Does __default_evpn__.evpn.0 only contain type 1 and type 4 route types ?
I have only vMX which is not stable. Sometimes I can see type 2 and type 3, sometimes I do not see any entries. (I do not have multi-home configured)
In QFX10008, I do not see any entries as follows:

__default_evpn__.evpn.0: 0/0/0/0
Anyone can clarify this for me ?
thanks !!
