what to advertise in BGP on p2p links

[carl_townshend]

Hi all

when I have my 2 internet routers that each connect to a separate ISP routers with /30 links to each, do I need to advertise these /30 links in the BGP network statement? will the ISP also advertise these or do I just need to do it on my routers?

cheers

Hi Carl

You need to advertise only the public prefix pool allocated to you which you want to advertise

You don't need to advertise the connected /30 interface. ISP will take care of it

Hi Carl,

i would advertise as reference for your IGP.

Update: on both the ends regardless the functional configuration (active, passive - primary secondary, primary primary and so on..)

Would I only do this on one end normally or both ?

cheers
