Examples: Configuring the MED Metric

Set the MED metric to 20 for all routes advertised in BGP update messages except for those sent to the peer system 192.168.0.1; the MED for this peer is 10:

[edit]
routing-options {
router-id 10.0.0.1;
autonomous-system 23;
}
protocols {
bgp {
metric-out 20;
group 23 {
type external;
peer-as 56;
neighbor 192.168.0.1 {
traceoptions {
file bgp-log-peer;
flag packets;
}
log-updown;
metric-out 10;
}
}
}
}

Set the MED metric to 20 for all routes from a particular community:

[edit]
routing-options {
router-id 10.0.0.1;
autonomous-system 23;
}
policy-options {
policy-statement from-otago {
from community otago;
then metric 20;
}
community otago members [56:2379 23:46944];
}
protocols {
bgp {
import from-otago;
group 23 {
type external;
peer-as 56;
neighbor 192.168.0.1 {
traceoptions {
file bgp-log-peer;
flag packets;
}
log-updown;
}
}
}
}
