Hello fellow birdies, I'm having some difficulty connecting the nodes.
Our network provides free IP Transit service so we need to carry downstream. We use OpenVPN/Wireguard connection between our nodes. We plan to use VLAN on OpenVPN or use GRE on Wireguard. This way, we have 2 interfaces tunnel1 and tunnel2 between each node. We created a bgp_v6 (IBGP) session on tunnel1 that allows downstream BGP sessions like HE(Hurricane Electric) and put the routing table into table 147. Create bgp_v6_own(IBGP) on tunnel2 to transmit those routing tables from BGP that cannot carry downstream to Table 247 Then we use ip rule Direct traffic to the correct routing table based on the interface. My English is not very good so I drew a picture for a description. link : https://i.postimg.cc/dtBDC4kh/photo-2022-07-12-12-54-28.jpg [image: image.png] The problem I'm having is that in IXP all BGP sessions differ only by IP or MAC. For instance: We have only one interface for BGP: ens18 And our IP Address is: 2a0f:5707:ffe3::57 AS141011 Our customers assume is: 2a0f:5707:ffe3::1 AS1 Our upstream which allowed downstream:2a0f:5707:ffe3::30 AS6939 Therefore we have a BGP session with AS1 and a BGP session with AS6939 AS6939 > Table 147 How should we get traffic from our downstream AS1 into Table 147? We have discussed using VLANs, but VLANs are usually not allowed in IXPs. The second solution is to use the ip rule to put every prefix from the downstream into Table 147, which is very inefficient. Do you have a better solution?
