MPLS网络中RSVP - TE与SPRING技术解析
1. RSVP - TE基础与LSP追踪
在MPLS网络中,RSVP - TE(Resource Reservation Protocol - Traffic Engineering)用于建立标签交换路径(LSP)。以下是一个记录路由信息的示例:
Record Route:
IPv4 10.0.0.11, flags 0x0
RP/0/0/CPU0:P2#show mpls forwarding labels 24008
Wed Nov 26 10:58:09.822 UTC
Local Outgoing Prefix Outgoing Next Hop Bytes
Label Label or ID Interface Switched
------ ----------- ---------- ------------ ---------- --------
24008 Pop 44 Gi0/0/0/5 10.0.0.11 192900
同时,还展示了IOS XR中MPLS RSVP - TE的traceroute示例:
