BGP network missing mask

Re: BGP network missing mask
Ok guys I'd like to hit you up with another general question. static routes take precedence over any routes learned from an IGP correct? What I am seeing here in my config is that there are a bunch of static routes. We also have the "network" command within BGP. We have 20 static routes. Five of the static routes all point… -
Re: BGP network missing mask
Thanks for the fast reply. So leaving out the mask would only fail if the network was subnetted? network 192.168.10.0 mask 255.255.255.224 Now, if the IT guy got lazy, and left out the mask, then BGP would assume a full class C. network 192.168.10.0 mask 255.255.255.0 And this would probably lead to undesired results.… -

Re: BGP network missing mask
That's a quesiton for whoever designed the network. The network command is used to announce routes to other BGP peers, but BGP won't put a route into the BGP table unless it has a valid next hop. So let's say I announce 131.12.16.0/24, but I don't have that route in my routing table. I won't announce it to my peers. Why?… -
Re: BGP network missing mask
You're probably over thinking it. BGP is a pretty simple protocol in operation. It's logic as to whether or not it considers a connection ebgp or ibgp is pretty binary - does the AS number match? if yes, ibgp, if no, ebgp. There are a few tricks that fudge with those rules, but I don't think you're quite there yet. If… -
Re: BGP network missing mask
Thank you gentlemen I will try both suggestions. Here's another quick general question for you guys. Is eBGP only between your edge network to the ISP? Let's say you are a service provider and you have clients that have their own AS. If they are hanging off your internal equipment. Would your "BGP" to them be considered… -
Re: BGP network missing mask
Ok here's another question.... Riddle me this.... (R1) ---iBGP--- (R2) ---eBGP--- (R3) R1 is seeing the network from R3 coming from R2. When I do a "sh ip bgp neighbor x.x.x.x(R2) received-routes" on R1, I am seeing the network from R3. But the network isn't being injected into the BGP table in R1. There are no fancy… -
