How to write the route received by BGP to the specified routing table instead of the default routing table.
I tried the following configuration, but it didn't work.

shell>ip link add name red type vrf table 10
shell>ip link set red up

router bgp 1 vrf red
 no bgp ebgp-requires-policy
 neighbor 172.16.3.204 remote-as 2
 !
 address-family ipv4 unicast
  network 6.6.6.0/24
 exit-address-family

router bgp 2 vrf red
 no bgp ebgp-requires-policy
 neighbor 172.16.3.205 remote-as 1
 !
 address-family ipv4 unicast
  network 5.5.5.0/24
 exit-address-family

link type vrf - it's bridge. The next you must add L3 interface to vrf. For several linux some different ways, but:

1. vrf interface with correct iproute2 table must be set and up
2. L3 interface (tunnel, GRE, IPIP, etc) must be attached to ip link set master
3. Check correct ip routes here. Sometimes need ip a delete, ip a add again after set master (for correct routes install).
4. Here you can see sh int brief under vtysh correct vrf - iface matching.
5. So next you can build bgp..

After 3. you should check by ping from remote side - correct setting will be answer to ping (of course even not ubuntu dummy interface type -) ).

Also you can got rake with kernel params rp_filter.. setup to 0 even you didn't know what you need -).

Also if you want the next mpls, stay away from wireguard, ipip and simple types of interfaces - they are support just clear IP..

Look for example

gw1.lab# sh int brief
Interface       Status  VRF             Addresses
---------       ------  ---             ---------

lan2            up      default         192.168.2.1/24
docker0         up      default         192.168.255.129/25

Interface       Status  VRF             Addresses

tun-red-1       up      vrf_red         192.168.0.0/31
vrf_red         up      vrf_red
vrf_red-lo      up      vrf_red      192.168.254.2/32

Interface       Status  VRF             Addresses
---------       ------  ---             ---------
vrf_blue        up      vrf_blue
