It is NOT a transitive attribute on eBGP peers. So you could set it all you
want, but it won't do anything towards the outside of your AS!

It's something either set INBOUND from eBGP peers, or OUTBOUND to iBGP
peers. (which one may wonder why you don't change local pref for your own
router, but want to on other routers in your ASN, but stranger things have
happened!)

Subject: Local Preference

Hi group,

I have a little doubt, can I apply the local preference inside/outside? or
only inside?.

Sample:

1)

route-map LP

mat community xx

set local preference XX

router bgp XX

neig x.x.x.x route-map LP in

2)

route-map LP

mat community xx

set local preference XX

router bgp XX

neig x.x.x.x route-map LP out

Please, let me know the opinion.

Thanks
