How to let Vyos route traffic via BGP

I was getting a handle on BIRD. But once switch to Vyos, not quite sure how it works. I have IPv6 BGP neighbor setup and I could see all the routes and IP address assigned to eth1(LAN) and eth0(WAN), but I still can't ping anything.

Please help me understand how Vyos deal with BGP. I am using https://tunnelbroker.li/

Vyos 1.3

my BGP configure

set protocols bgp 203xxxaddress-family ipv6-unicast network 2a0c:[my ip block]/48

set protocols bgp 203xxx neighbor 2a0c:9a40:100f:384::1 address-family ipv6-unicast

set protocols bgp 203xxx neighbor 2a0c:9a40:100f:384::1 remote-as '34927'

set protocols bgp 203xxx neighbor 2a0c:9a40:100f:384::1 update-source 'tun0'

set protocols bgp 203xxx parameters router-id '``38.13.``x.x'

Configure

vyos@EdgeRouterX-2012:~$ show configuration commands | match route6

set protocols static interface-route6 fe80::200:5efe:b92c:5311/128 next-hop-interface tun0

set protocols static route6 2a0c:[my ipv6 block]::/48 blackhole distance '254'
