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 ‘100.64.52.10/24’
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 ‘6.6.6.6/32’
set protocols bgp address-family ipv4-unicast network 6.6.6.6/32
set protocols bgp neighbor 192.168.2.107 address-family ipv4-unicast
set protocols bgp neighbor 192.168.2.107 ebgp-multihop ‘5’
set protocols bgp neighbor 192.168.2.107 remote-as ‘50812’
set protocols bgp neighbor 192.168.2.107 update-source ‘100.64.52.10’
set protocols bgp parameters log-neighbor-changes
set protocols bgp parameters router-id ‘100.64.52.10’
set protocols bgp system-as ‘64666’
set protocols static route 0.0.0.0/0 next-hop 100.64.52.1
set protocols static route 192.168.2.0/24 next-hop 100.64.52.1

routing table of Vyos

vyos@vyos:~$ show ip route

L 192.168.2.107/32 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 6.6.6.6 address?

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