Hi Brian
R9#sh run | b ^router isis router isis net 49.0009.9999.9999.9999.00 metric-style wide transition summary-address 10.6.0.0 255.255.254.0 level-1-2 passive-interface Loopback0 passive-interface Loopback1 passive-interface Loopback2 results in R9#sh isis data de IS-IS Level-1 Link State Database: LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OL R9.00-00 * 0x0000000A 0xDF6B 1164 1/0/0 Auth: Length: 9 Area Address: 49.0009 NLPID: 0xCC Hostname: R9 IP Address: 10.6.0.1 Metric: 10 IP 150.50.69.0/30 Metric: 0 IP 200.0.0.9/32 Metric: 0 IP 10.6.0.0/24 <======= Metric: 0 IP 10.6.1.0/24 <======= R9.00-00 * 0x0000000A 0x0F8A 1162 0/0/0 Area Address: 49.0009 NLPID: 0xCC Hostname: R9 IP Address: 10.6.0.1 Metric: 10 IS-Extended R6.00 Metric: 10 IP 150.50.69.2/32 Metric: 10 IP 150.50.69.0/30 Metric: 0 IP 200.0.0.9/32 Metric: 0 IP 10.6.0.0/23 <======= So the command "summary-address 10.6.0.0 255.255.254.0 level-1-2" does not do what i it pretends to do. The command summary-address 10.6.0.0 255.255.254.0 level-1 had no effect at all. You have been right. Is this a bug and the solution would be ok, or is this one of the cases where I should know that the command does not do what it should do. Does the guy (script) who does the grading look at the config or at the result? greatings -peter
