Info

This configuration assumes that you use community 65500:1234 as a standard way to suppress announcements of these routes outside your AS. The community is included as a precaution to provide a backup method to make sure that the routes stay within your AS in case, for some reason, the NO_EXPORT action fails. Then define a simple regular expression to match the Team Cymru private AS number: [edit policy-options] aviva@RouterF# set as-path cymru-private-asn 65333 The following routing policy for the EBGP peering session accepts the bogon route updates: [edit policy-options] aviva@RouterF# edit policy-statement cymru-bogon-list [edit policy-options policy-statement cymru-bogon-list] aviva@RouterF# set term 1 from protocol bgp aviva@RouterF# set term 1 from as-path cymru-private-asn aviva@RouterF# set term 1 from community cymru-bogon-community aviva@RouterF# set term 1 then community add dont-announce aviva@RouterF# set term 1 then next-hop 192.0.2.1 aviva@RouterF# set term 1 then accept aviva@RouterF# set then reject The from clause matches BGP routes from the AS path defined in cymru-private-asn (that is, from AS number 65333) and that contain the community string defined in cymru-bogon-community (that is, 65333:888). The then clause performs two actions on any matching routes before accepting them. The set then community add dont-announce command attaches the community string 65500:1234 to the routes to ensure that the routes are never forwarded outside the local AS. (This is the community you defined with the set community dont-announce command.) The second action in the then clause sets the route’s next hop to 192.0.1.2, which is a reserved network prefix. This next hop maps the bogons to a remotely triggered black hole, which acts as a filter for the bogons, discarding them and explicitly stating that they are never to be readvertised. You define this prefix as a static route in the routing table: [edit routing-options] aviva@RouterF# set static route 192.0.2.1/32 discard aviva@RouterF# set static route 192.0.2.1/32 no-readvertise aviva@RouterF# set static route 192.0.2.1/32 retain The discard option on the static route prevents it from being forwarded, noreadvertise prevents it from being readvertised to anyone else, and retain keeps the route in the forwarding table if the JUNOS routing process restarts normally. If you are using the default JUNOS martians, 192.0.2.1/32 is a martian and will be rejected, so you need to explicitly allow the routing table to accept it: [edit routing-options] aviva@RouterF# set martians 192.0.2.1/32 exact allow 468 | Chapter 13: BGP This is the Title of the Book, eMatter Edition Copyright © 2008 O’Reilly & Associates, Inc. All rights reserved.
When setting up policies, also create a second one for the EBGP peering session to make sure your network doesn’t forward any routing information back to Team Cymru: [edit policy-options] aviva@RouterF# set policy-statement deny-all then reject Now you have all the pieces in place to configure the EBGP peering session with Team Cymru so you can receive the automatic bogon updates. As with establishing a peering session with any remote AS, you need to contact the AS administrator to set up the peering terms and to provide your AS number, the IP address of the router’s interface that will be used for peering, and your MD5 password. With this information you can configure the EBGP peer. The basic configuration establishes the external peering, sets a description for the peer, defines the peer’s AS number and the remote IP address used for the peering session, and sets a mutually agreed upon MD5 key: [edit protocols bgp group cymru-peering] aviva@RouterF# set type external aviva@RouterF# set description "bogon update peering with team cymru" aviva@RouterF# set peer-as 65333 aviva@RouterF# set neighbor 10.0.31.1 aviva@RouterF# set authentication-key "$9$D8imfQFnCp0zFreM87Nmf5T/C" Apply the routing policies: [edit protocols bgp group cymru-peering] aviva@RouterF# set import cymru-bogon-list aviva@RouterF# set export deny-all The import policy accepts the bogon list, and the export policy prevents the router from sending any routing updates to Team Cymru. Because Team Cymru is more than one BGP hop away from your network, the EBGP peering needs to be a multihop session: [edit protocols bgp group cymru-peering] aviva@RouterF# set multihop ttl 255 The time to live (TTL) specifies how many hops your router is from the EBGP neighbor. For an EBGP session where the external neighbor is directly connected, the TTL is 1. For multihop sessions, the default TTL is 64. This configuration sets the TTL to the maximum allowable value of 255 to ensure that the peering succeeds. BGP places the TTL value in the packet’s IP header. A final portion of the EBGP peer configuration restricts the number of routes Team Cymru can advertise to you, to guard against a misconfiguration or an inadvertent advertisement of the entire Internet routing table: [edit protocols bgp group cymru-peering] aviva@RouterF# set family inet unicast prefix-limit maximum 100 aviva@RouterF# set family inet unicast prefix-limit teardown 100 Adding a BGP Community to Routes | 469 This is the Title of the Book, eMatter Edition Copyright © 2008 O’Reilly & Associates, Inc.
