Dear all,
I have installed nlsr and try to configure it. However, the prefixes
are found not to be advertised properly. Is there any setting like allowing
certain port? Before using nlsr, nfdc is used and everything works well.
Could someone help me check the problem?
My configurations are below:
3 routers are connected to each other: /thu/elop1/%C1.Router/router1
/thu/elop2/%C1.Router/router2 and /thu/elop3/%C1.Router/router3
The results of nfd-status -r is as below:
*RIB:*
* /localhost/nfd/rib route={faceid=258 (origin=0 cost=0 ChildInherit)}*
* /thu/elop3/%C1.Router/router3 route={faceid=260 (origin=128 cost=25
RibCapture)}*
* /thu/elop2/%C1.Router/router2 route={faceid=261 (origin=128 cost=30
RibCapture)}*
* /thu/elop1/%C1.Router/router1 route={faceid=270 (origin=0 cost=0
RibCapture)}*
* /thu/elop/%C1.Router/router3 route={faceid=260 (origin=128 cost=25
RibCapture)} (This name is from old settings)*
* /thu/elop/%C1.Router/router2 route={faceid=261 (origin=128 cost=30
RibCapture)} (**This name is from old settings**)*
* /thu/NLSR/sync route={faceid=260 (origin=128 cost=25 RibCapture),
faceid=261 (origin=128 cost=30 RibCapture)}*
* /thu/NLSR/LSA/elop1/%C1.Router/router1 route={faceid=270 (origin=0
cost=0 RibCapture)}*
* /thu/NLSR/LSA route={faceid=260 (origin=128 cost=25 RibCapture),
faceid=261 (origin=128 cost=30 RibCapture)}*
* /ndn/broadcast/KEYS route={faceid=260 (origin=128 cost=25 RibCapture),
faceid=261 (origin=128 cost=30 RibCapture), faceid=270 (origin=0 cost=0
RibCapture)}*
