在Cisco IOS XR 2.1及后续版本中，引入了为每个虚拟私有网络(VPN)路由/转发(VRF)实例单独配置路由器ID的功能。此特性允许在同一路由器上进行VRF到VRF的边界网关协议(BGP)对等互联，通过在现有bgp router-id命令中新增关键字实现每个VRF拥有独立的路由器ID。

Per-VRF Router ID Assignment

In Cisco IOS XE Release 2.1 and later releases, support for configuring separate router IDs for each Virtual Private Network (VPN) routing/forwarding (VRF) instance was introduced. The Per-VRF Assignment of BGP Router ID feature introduces the ability to have VRF-to-VRF peering in Border Gateway Protocol (BGP) on the same router. BGP is designed to refuse a session with itself because of the router ID check. The per-VRF assignment feature allows a separate router ID per VRF using a new keyword in the existing bgp router-id command. The router ID can be manually configured for each VRF or can be assigned automatically either globally under address family configuration mode or for each VRF.
