Hi. Is it possible to use alias ethernet in mpls LSPs? I'm trying the following: # ifconfig ... eth2 Encapsulamento do Link: Ethernet Endere=E7o de HW 00:40:05:31:45:27 inet end.: 192.168.28.1 <http://192.168.28.1> Bcast:192.168.28.31<http://192.168.28.31>Masc: 255.255.255.224 <http://255.255.255.224> UP BROADCASTRUNNING MULTICAST MTU:1500 M=E9trica:1 RX packets:65275 errors:78 dropped:0 overruns:0 frame:2 TX packets:68281 errors:0 dropped:0 overruns:0 carrier:0 colis=F5es:12900 txqueuelen:1000 RX bytes:72749368 (69.3 MiB) TX bytes:54638965 (52.1 MiB) IRQ:10 Endere=E7o de E/S:0xe000 eth2:1 Encapsulamento do Link: Ethernet Endere=E7o de HW 00:40:05:31:45:27 inet end.: 192.168.29.1 <http://192.168.29.1> Bcast:192.168.29.31<http://192.168.29.31>Masc: 255.255.255.224 <http://255.255.255.224> UP BROADCASTRUNNING MULTICAST MTU:1500 M=E9trica:1 IRQ:10 Endere=E7o de E/S:0xe000 ... # mpls nhlfe add key 0 Key: 0x00000006 # mpls nhlfe change key 6 instructions push gen 10000 nexthop eth2 ipv4 192.168.28.2 <http://192.168.28.2> # mpls nhlfe show NHLFE entry key 0x00000006 mtu 1496 propagate_ttl push gen 10000 set eth2 ipv4 192.168.28.2 <http://192.168.28.2> (0 bytes, 0 pkts, 0 dropped) # mpls nhlfe add key 0 Key: 0x00000007 # mpls nhlfe change key 7 instructions push gen 10001 nexthop eth2:1 ipv4 192.168.29.2 <http://192.168.29.2> RTNETLINK answers: Operation not permitted # mpls nhlfe show NHLFE entry key 0x00000007 mtu 0 propagate_ttl (0 bytes, 0 pkts, 0 dropped) NHLFE entry key 0x00000006 mtu 1496 propagate_ttl push gen 10000 set eth2 ipv4 192.168.28.2 <http://192.168.28.2> (0 bytes, 0 pkts, 0 dropped) eth2 works fine, but eth2:1 does not. Does anybody knows what "RTNETLINK answers: Operation not permitted" means? TIA. |
