My BGP router is Mikrotik, i had a e-BGP with “IIG1”, Now i need to make another e-BGP with “IIG2”. i had
advertised “xxxxxx/22” in “IIG1” and now “yyyyy/24” in to new “IIG2”.
Do i need to add another instance & AS number for “IIG2” ?
no, just add another peer. use “/routing filter” to determine which prefixes get annouced / received from which peer.
It’s not working. May be i missed something in my routing filter rules,
plz need urgent help,

whats not working ?
You should use set-bgp-prepend=, not put your as number in there. Prepend is 1, 2, 3, 4, etc … how many times it will prepend your AS number. Right now you are probably prepending your AS about 14000 times : )
You should use a action=discard at the end to drop the rest of the prefixes you do not want.
What’s not working ?
How can i discard everything at end..
i have add
/routing filter add chain=btcl-out prefix=xxxxx/22 prefix-length=22-32 action=passthrough
/routing filter add chain=btcl-out prefix=0.0.0.0/0 prefix-length=0-32 action=discard
but it’s disacard everything, also prefix xxxxx/22

action=passthrough should be action=accept. passthru just goes right thru, no action at all…
