Cisco ASR 900 Series User Manual

Configuring Co-routed Flex LSPs
Before you begin
•
You must have symmetric source and destination TE router IDs in order for bidirectional LSPs to be
associated.
•
Tunnels attributes must be configured identically on both sides of co-routed bidirectional LSP.
Up to 250 Flex LSP tunnels are supported.Note
Procedure
1. Enable basic MPLS Traffic Engineering on hostname PE1:
mpls traffic-eng tunnels
mpls traffic-eng fault-oam
mpls traffic-eng nsr
router ospf 100
router-id 1.1.1.1
nsr
mpls traffic-eng router-id Loopback0
mpls traffic-eng area 0
2. Map L2VPN pseudowire to a specific Flex LSP tunnel:
template type pseudowire mpls-te1 (mpls-te1 can be any name)
encapsulation mpls
preferred-path interface Tunnel1 disable-fallback
bandwidth 100
template type pseudowire mpls-te4
encapsulation mpls
preferred-path interface Tunnel4 disable-fallback
bandwidth 100
3. Configure Flex LSP:
interface Tunnel1
bandwidth 1000
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 22.22.22.22
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng priority 7 7
tunnel mpls traffic-eng bandwidth 1000
tunnel mpls traffic-eng path-option 1 explicit name BDI1 bandwidth 1000
tunnel mpls traffic-eng path-option protect 1 explicit name BACKUP1 bandwidth 1000
tunnel mpls traffic-eng bidirectional association id 1 source-address 11.11.11.11 global-id
1
tunnel mpls traffic-eng bidirectional association type co-routed
ip explicit-path name BDI1 enable
next-address 1.11.1.1
next-address 10.1.2.2
next-address 2.22.1.22
ip explicit-path name BACKUP1 enable
next-address 10.3.11.1.10
next-address 10.4.22.22
4. Enable BFD
