Configuring Ldp To Redistribute Bgp Unicast Routes; Configuring An Lsp Generation Policy - HP FlexNetwork 10500 Series Configuration Manual

Step
2. Enter LDP view or enter
LDP-VPN instance view.
3. Enable LDP MD5
authentication.
Configuring LDP to redistribute BGP unicast
routes
By default, LDP automatically redistributes IGP routes, including the BGP routes that have been
redistributed into IGP. Then, LDP assigns labels to the IGP routes and labeled BGP routes, if these
routes are permitted by an LSP generation policy. LDP does not automatically redistribute BGP
unicast routes if the routes are not redistributed into the IGP.
For example, on a carrier's carrier network where IGP is not configured between a PE of a Level 1
carrier and a CE of a Level 2 carrier, LDP cannot redistribute BGP unicast routes to assign labels to
them. For this network to operate correctly, you can enable LDP to redistribute BGP unicast routes. If
the routes are permitted by an LSP generation policy, LDP assigns labels to them to establish LSPs.
For more information about carrier's carrier, see
To configure LDP to redistribute BGP unicast routes:
Step
1. Enter system view.
2. Enter LDP view or enter
LDP-VPN instance view.
3. Enable LDP to redistribute
BGP IPv4 unicast routes.
4. Enable LDP to redistribute
BGP IPv6 unicast routes.

Configuring an LSP generation policy

LDP assigns labels to the routes that have been redistributed into LDP to generate LSPs. An LSP
generation policy specifies which redistributed routes can be used by LDP to generate LSPs to
control the number of LSPs, as follows:
•
Use all routes to establish LSPs.
•
Use the routes permitted by an IP prefix list to establish LSPs. For information about IP prefix
list configuration, see Layer 3—IP Routing Configuration Guide.
