NLSR

Hello! I encounter several problems while NLSR runs.
Hope that I can get some inspirations here.

I configured two NDN routers, Router A and Router B, and observe the sync packets between them.
The following is the topology. Host 1 and Host 2 connect to Router A. Host 3 and Host 4 connect to Router B.
All the host are configured to a router manually.

1. At first, the sync packets of Router A and Router B transmit well. This means the connection between Router A and B is up.
   But, Router A and B do not share their RIB to each other, which means Host 1 and 2 cannot reach Host 3 and 4. It is because Router A does not know where Host 3 and 4 are.
   Due to NLSR protocol, I know that the routing information will be synchronized after written to LSDB. I guess this may be the reason why Host 1 cannot reach to Host 3.
   But, I have no idea that how to make the RIB written to LSDB and show the LSDB for checking.
   I am also not sure whether my guess is correct or not. Please give me some advises and help.

2. I observed the sync packets between RA and RB continually. I found that the sync Interest packets of RA show "NoRoute", but I can ping RB successfully. The more weird thing is RB still gets the sync Interest packets of RA which contains "NoRoute" message. I am confused that why the sync Interest packets of RA show "NoRoute", but they are still received by RB. Is there anyone get the same problem?

The following is the sync Interest packet of RA that received by RB.
