Customizing OSPF Services
117356-A Rev. A 7-21
In Figure 7-2, for example, boundary router A running OSPF and BGP learns
external routes via BGP:
1. Router R14 generates an ASE describing the route. OSPF fills in the external
route tag with BGP-specific information according to RFC 1403.
2. Router A injects the ASE into the AS, and OSPF routers flood the ASE
throughout the AS.
3. Router R1, which runs OSPF and BGP, receives the ASE. Router B generates
a BGP update, using the contents of the external route tag to set the Origin
and AS Path attributes in the update.
