Cannot ping to loopback

Hello guys,
I have a question for connectivity between cisco and vyos
2 router are in BGP peering and I made a loopback interface in vyos.
Cisco could get this route but can’t reach to it

This is a configuration and each routing table

set interfaces ethernet eth0 address ‘’
set interfaces ethernet eth0 hw-id ‘00:50:56:aa:2b:e3’
set interfaces ethernet eth1 hw-id ‘00:50:56:aa:c8:9b’
set interfaces ethernet eth2 hw-id ‘00:50:56:aa:ad:24’
set interfaces loopback lo address ‘’
set protocols bgp address-family ipv4-unicast network
set protocols bgp neighbor address-family ipv4-unicast
set protocols bgp neighbor ebgp-multihop ‘5’
set protocols bgp neighbor remote-as ‘50812’
set protocols bgp neighbor update-source ‘’
set protocols bgp parameters log-neighbor-changes
set protocols bgp parameters router-id ‘’
set protocols bgp system-as ‘64666’
set protocols static route next-hop
set protocols static route next-hop

routing table of Vyos

vyos@vyos:~$ show ip route

S>* [1/0] via, eth0, weight 1, 01w6d21h
C>* is directly connected, lo, 00:16:58
C>* is directly connected, eth0, 01w6d21h
S>* [1/0] via, eth0, weight 1, 6d20h34m

routing table of cisco

NR-IB-VEN-B2-01#show bgp vrf vrf-mngmt neighbors routes

 Network          Next Hop            Metric LocPrf Weight Path

Route Distinguisher: 1:1 (default for vrf vrf-mngmt)
*> 0 0 64666 i

S* [1/0] via is variably subnetted, 2 subnets, 2 masks
C is directly connected, Port-channel1.4000
L is directly connected, Port-channel1.4000

This is weird, even if cisco get a bgp route, but I cann’t see any route in routing table.

I captured the packet in vyos but couldn’t see any ping packet

Devices are not connected directly… Router in the middle knows the route for address?

Thank you your reply. actually there were some problme of BGP neighbor!
