So what you mean is that, the purpose of default-information originate command is to advertise default-route if the default-route was received from IGP like OSPF/EIGRP or if it was statically configued? Keys are the local ASNs/processes (Integer), values are the data for that process (Hash). However, it does accept when adding the address family which it will then inject it under the address family instate of BGP, R7(config-router)#neighbor 10.10.100.14 default-originate, % Policy commands not allowed without an address family. If you need to change them, you can do so here. In the case of BGP, if you are using the "default-information originate" the default route must be in the routing table, but if using the "neighbor x.x.x.x default-originate" in front of a neighbor the default route doesn't need to be in the routing table.

View name (typically not used) is significant to Quagga only, and simply means, the result of route selection does not go to the kernel routing table. Prior to January 2009, BGP autonomous system numbers that were allocated to companies were 2-octet numbers in the range from 1 to 65535 as described in RFC 4271, A Border Gateway Protocol 4 (BGP-4). Router A has a static route for 0.0.0.0, and neighbor default-originate. I just want to ask what is the difference between the two? R14 still taken the default route which is configured with. Second, I follow you up to the point of the prefix list.

While (1) - having a static default route on this box - it an obvious workaround in this simplified case, I am going to be making this setup I can't make my edge router advertise 0.0.0.0 to iBGP peers if I don't use a static route pointing to ISP then redistribute it to BGP? show ip bgp flap-statistics: More Show IP BGP: show ip bgp neighbor [peer]: More Show IP BGP: show ip bgp regexp line: Display BGP Routes by AS Path: show ip bgp regexp line: More Show IP BGP: show ip bgp summary: More Show IP BGP: show ip bgp view name: Viewing the view: show ip bgp vpnv4 all: BGP Address Family: show ip bgp X:X::X:X: Show IP BGP We will do our best to cover the majority of BGP, but as you might know, there is a lot to it. I am glade that you are building it up right, but please note that BGP never advertise a default route (iBGP or eBGP) unless one of the 3 actions explained above is taken. Actually, not only one ISP router was configured this way. Now I get it. We have lots ISPs and we are only asking those ISPs to advertise default routes to our network. log file /var/log/quagga/bgpd.log While OSPF has the always keyword, BGP doesn't.

This propagates the default route to the hosts and the switch. Another way of advertising a default route to a specific BGP neighbor is by issuing the neighbor default-originate command. The default-information originate command is used to configure a BGP routing process to advertise a default route (network 0.0.0.0).
