[c-nsp] Nexus BGP Default local-preference

[Stoward, Matt]

I've been looking at the online doco's (including the wiki on IOS->Nexus config), I can't find where/if I can do default local preference within the BGP configuration.
All the command references that I can find references using a set command within a route-map per neighbour, but I can't find a global setting (in a terribly nested BGP config mode).

Is this command actually available ? I'm using 5.0(3).


Regards,
Matt

Hey Matt,

Default BGP NX-OS distance are following: EBGP*—*20, IBGP—200

Distance configuration is a sub command under address-family.

http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/unicast/command/reference/n7k_unicast_cmds_5x.html

*distance **ebgp-route ibgp-route local-route*—Configures a rating of the
trustworthiness of a routing information source, such as an individual
router or a group of routers. BGP does not use discard routes for next-hop
resolution. In general, the higher the value, the lower the trust rating. An
administrative distance of 255 means the routing information source cannot
be trusted at all and should be ignored. Use this command if another
protocol is known to be able to provide a better route to a node than was
actually learned via external BGP (eBGP), or if some internal routes should
be preferred by BGP. Range: 1 to 255. Default: EBGP*—*20, IBGP—200.

I believe the OP seeks information on LOCAL_PREF, not route
preference/administrative distance.

Right sorry, AFAIK you cannot change the default LOCAL PREFERENCE 100
