R2511-HP MSR Router Series MPLS Configuration Guide(V5)

Configuration prerequisites
Before you configure a static LSP, complete the following tasks:
• Determine the ingress LSR, transit LSRs, and egress LSR for the static LSP.
• Enable MPLS on all these LSRs.
• Make sure the ingress LSR has a route to the FEC destination. This is not required on the transit LSRs
and egress LSR.
Configuration guidelines
Follow these guidelines when you configure a static LSP:
• Do not specify a P2MP interface (such as a P2MP-type ATM subinterface or frame relay
subinterface) as the outgoing interface. Otherwise, the static LSP cannot be up.
• On the ingress LSR, the specified next hop or outgoing interface must be consistent with the next hop
or outgoing interface of the optimal route in the routing table. If you configure a static IP route for
the LSP, be sure to specify the same next hop or outgoing interface for the static route and the static
LSP. For information about configuring a static IP route, see Layer 3—IP Routing Configuration
Guide.
• For an ingress or transit LSR, do not specify the public address of an interface on the LSR as the next
hop address.

8. Configure a static LSP taking
the current LSR as the ingress.
static-lsp ingress lsp-name
destination dest-addr { mask |
mask-length } { nexthop
next-hop-addr | outgoing-interface
interface-type interface-number }
out-label out-label
The outgoing-interface keyword is
available only on point-to-point
connections.
9. Configure a static LSP taking
the current LSR as a transit
LSR.
static-lsp transit lsp-name
incoming-interface interface-type
interface-number in-label in-label
{ nexthop next-hop-addr |
outgoing-interface interface-type
interface-number } out-label
out-label
The outgoing-interface keyword is
available only on point-to-point
connections.
10. Configure a static LSP taking
the current LSR as the egress.
static-lsp egress lsp-name

interface-number in-label in-label

Establishing dynamic LSPs through LDP
Perform the tasks in this section so the device can use LDP to set up dynamic LSPs.
