first rif has a length of eight bytes but the length field says 24.
A correct RIF would be C820.0123.0321.0050. This is read as:
110 - single route broadcast (spanning explorer)
01000 - length of eight
0 - read left to right
010 - max length of 2052 bytes
0000 - not used
000000010010 - ring 012 (18 decimal)
0011 - bridge 3
000000110010 - ring 032 (50 decimal)
0001 - bridge 1
000000000101 - ring 5
0000 - bridge 0 (destination)
The second RIF has a length of eight but the length field says six.
A correct RIF would be 0830.0011.0191.0030. This would be read:
000 - Non-Broadcast
01000 - length of eight
0 - direction is left to right
011 - max 4472 bytes
0000 - not used
000000000001 - ring 1
0001 - bridge 1
000000011001 - ring 19 (25 decimal)
0001 - bridge 1
000000000011 - ring 3
0000 - bridge 0 (destination)
