[j-nsp] LDP basic discovery packets

[Daniel Roesen]

Hi,

JunOS is sourcing LDP basic discovery PDUs from the egress interface
IP as source. Can this be changed to use the router-id?

This would help filtering extremely. Currently, short of listing every
remote backbone interface IP as valid LDP discovery source (with
224.0.0.2 as destination IP), one can just allow unconditionally LDP
packets to 224.0.0.2 to allow LDP basic discovery to work.

Extended discovery (unicast) PDUs are already sent with the loopback IP
as source (at least if default-address-selection is enabled).


Best regards,
Daniel
