[mpls-linux-general] Dubts

[Miquel C. P. <u10...@co...>]

Hello, I have any dubts in protocol LDP, the first is:

LDP_2# show ldp data
  192.168.0.0/24  local binding:   label: gen 10000
  192.168.3.0/24  local binding:   label: gen 10001
  192.168.0.0/24  remote binding:  no outlabel lsr: 192.168.0.1:0
  192.168.1.0/24  remote binding:  no outlabel lsr: 192.168.0.1:0
  192.168.2.0/24  remote binding:  no outlabel lsr: 192.168.3.3:0
  192.168.0.0/24  local binding:   label: gen 10002
  192.168.3.0/24  local binding:   label: gen 10003
  192.168.3.0/24  remote binding:  no outlabel lsr: 192.168.3.3:0
  192.168.4.0/24  remote binding:  no outlabel lsr: 192.168.3.3:0

But, I assign the remote binding manually??

The second is , when run the ldpd:

What is nexthop ??? t'he 1.0.0.0 isn't ip of my LAN, 5.192.168.3 isn't too.
What is??

And the last, when execute the ripd deamon, I see the follow line:

[root@uni quagga]# ripd -d
2005/05/09 18:24:51 RIP: can't setsockopt SO_RCVBUF

The deamon run correctly, but I know the why?

thank you!!!
