I have a ccr1036 with two WAN links (two carriers). By one carrier I receive traffic to one prefix /24 (route traffic, no announce) public and by another carrier, I announce another prefix/24.
World → ISP 1 → WAN 1 (routing traffic) → 138.186.xxx.xxx/24 clients
World → ISP 2 → WAN 2 (BGP announce) → 190.103.xxx.xxx/24 clients
WAN 1 IP: 200.53.xxx.xxx/29
WAN 2 IP: 38.104.xxx.xxx/30
WAN 1 is my default gw (0.0.0.0/0 without mark).
In routes, I configured two routes to 0.0.0.0/0 with mark (one by wan 1 and another by wan 2).
When I execute mtr command from remote side (in example IP address is 167.61.73.190) to one client in prefix announce by ISP 2, I see one hope with WAN 1 IP address.
