  • 1.  vXLAN and MPLS stitching questions

    Posted 09-14-2021 18:48
    I have the following topology:

    Here is the BGP status
    root@vMX-1# run show bgp summary | find 192.168.1.44
192.168.1.44          64511        193        156       0       0     1:03:38 Establ
  bgp.evpn.0: 8/19/8/0
  vpn1.evpn.0: 8/14/8/0
  __default_evpn__.evpn.0: 0/0/0/0
  EVPN1.evpn.0: 0/3/0/0
  vpn2.evpn.0: 0/2/0/0

root@vMX-4# run show bgp summary | find 192.168.1.11
192.168.1.11          64511        171        212       0       0     1:09:17 Establ
  bgp.evpn.0: 5/17/5/0
  vpn1.evpn.0: 2/10/2/0
  __default_evpn__.evpn.0: 0/0/0/0
  vpn2.evpn.0: 0/4/0/0
  EVPN1.evpn.0: 2/14/2/0
​

    The vXLAN and MPLS is stitched as follows:

    My question is I should see the type 2 route shown in vpn1.evpn.0  also in EVPN1.evpn.0, right ? If not as follows, what might be possible issues ?

    root@vMX-1# run show route table vpn1.evpn.0 | match 10.150.10.1
2:192.168.1.2:2::10::00:05:86:71:9e:00::10.150.10.1/304 MAC/IP

root@vMX-1# run show route table EVPN1.evpn.0 | match 10.150.10.1

    thanks !!

    I verified that

    root@vMX-1# run show route table EVPN1.evpn.0 | find 10.150.10.1
2:192.168.1.11:4::10::00:05:86:71:b4:00::10.150.10.1/304 MAC/IP
                   *[EVPN/170] 00:02:02
                      Indirect
​

    thanks !!
