Changing MED Attributes
By default, Dell Networking OS uses the MULTI_EXIT_DISC or MED attribute when comparing EBGP paths from the same AS.
To change how the MED attribute is used, enter any or all of the following commands.
• Enable MED comparison in the paths from neighbors with dierent ASs.
CONFIG-ROUTER-BGP mode
bgp always-compare-med
By default, this comparison is not performed.
• Change the bestpath MED selection.
CONFIG-ROUTER-BGP mode
bgp bestpath med {confed | missing-as-best}
• confed: Chooses the bestpath MED comparison of paths learned from BGP confederations.
• missing-as-best: Treat a path missing an MED as the most preferred one.
To view the nondefault values, use the show config command in CONFIGURATION ROUTER BGP mode.
Changing the LOCAL_PREFERENCE Attribute
In Dell Networking OS, you can change the value of the LOCAL_PREFERENCE attribute.
To change the default values of this attribute for all routes received by the router, use the following command.
Border Gateway Protocol IPv4 (BGPv4)
