Hello,
so I setup case 2 of "EVI 2.0 EVPN Data Center Interconnect (EVPN DCI) deployment guide"
We have VM1 and VM2 connected to 5940-3 which will take their local distributed gateway. On 5940-3 I can see "host routes" from 5940-3.
dis ip ro vpn vpna
10.80.22.21/32 BGP 255 0 192.168.1.14 Vsi1000
10.80.23.21/32 BGP 255 0 192.168.1.14 Vsi1000
Imagine another Router "R" that is connected to WAN with OSPF and has e.g. loopback IP address of 192.168.20.34. Also the router has BGP configured.
How can I advertise the information of those host routes to that router? I tried a lot to get those routing information, BGP state is established of course, but I cannot any routes towards that router.
Let´s look at 5940-3:
bgp 100
peer 192.168.1.14 as-number 200
peer 192.168.1.14 connect-interface loopback 0
peer 192.168.1.14 ebgp-max-hop 64
peer 192.168.20.34 connect-interface loopback 0
address-family ipv4
peer 192.168.20.34 enable
address-family l2vpn evpn
peer 192.168.1.14 enable
peer 192.168.1.14 router-mac-local
And for mentioned router "R":
bgp 100
router-id 192.168.20.34
peer 192.168.1.13 connect-interface loopback 0
address-family ipv4
peer 192.168.1..13 enable
Some hints would be great.
