we switch the NE28、NE29 to the spare GNE NE111 strongly,the NE28 and NE29 loss the monitor ,it is mean the spare GNE invalid.
the structure of the network:
check the attachment1
1、the NE is monitor in the main GNE,the ECC is normal,so the SCC and the SCC software is ok,also we can escape the ECC setting parameter problem.
2、we check the max route distance of the NE is 20,the distance is smaller than the actual route,so the spare route fail.
3、we set the max route parameter of the NE to the default 64 in the u2000,and slove the problem.
we set the max route of the NE28、NE29 to 20,the distance between the action NE and the GNE is more than 20,so we can not find the spare route,the ECC is fail.
