Re: [mpls-linux-general] CR-LDP

[Mouli T <mou...@ya...>]

hi Mrugendra,
    Few days back we worked with LDP code version
0.060 and are able to establish Downstream on demand
Ordered LSP (by changing the options accordingly and
rebuilding ldp_linux executable).
    In the process we feel few fixes are needed to the
present code. they are 

While adding new route using add_route() in
ldp_linux.c
instead of 
  dest->next_hop.u.ipv4 = ntohl(inet_addr(net_str));
use 
  dest->next_hop.u.ipv4 = ntohl(inet_addr(nh_str));

while preparing attributes for a new route added using
Recognize_new_fec() r_attr is NULL and thus causing
segmentation fault in Prepare_Label_Request_Attributes
(ldp_label_request.c). We went for a quick fix by
setting s_attr fields to 1 whenever r_attr is NULL.

After doing the two fixes try establish LDP sessions
and add route in LDP at INGRESS. You should be able to
establish DoD ordered LSP successfully.

pl. give yr feedback....

Thanks,
Mouli.
