I was previously using frame-relay encapsulation to carry ipv6 traffic across logical tunnel interfaces in an MX.
I was doing it again recently and it doesn't seem to work on trio, either that or my memory is foggy. if someone has a better way to carry ipv6 across an lt-interface these days, I'm all ears. this is related to this discussion some time ago: http://www.gossamer-threads.com/lists/nsp/juniper/23524 so here's a frame relay lt interface on a 40x1Gbe dpc root@svo-e2-mx480-re0# run show interfaces lt-4/3/10 Physical interface: lt-4/3/10, Enabled, Physical link is Up Interface index: 282, SNMP ifIndex: 689 Type: Logical-tunnel, Link-level type: Logical-tunnel, MTU: Unlimited, Speed: 1000mbps Device flags : Present Running Interface flags: Point-To-Point SNMP-Traps Link flags : None Physical info : 13 Current address: 80:71:1f:94:8e:28, Hardware address: 80:71:1f:94:8e:28 Last flapped : 2011-05-08 21:48:35 UTC (6w2d 20:58 ago) Input rate : 0 bps (0 pps) Output rate : 0 bps (0 pps) Logical interface lt-4/3/10.0 (Index 70) (SNMP ifIndex 0) Flags: Point-To-Point SNMP-Traps 0x4000 DLCI 1 Encapsulation: FR-NLPID Input packets : 0 Output packets: 0 Protocol inet, MTU: 4470 Flags: Sendbcast-pkt-to-re Addresses, Flags: Is-Preferred Is-Primary Destination: 172.19.0.252/31, Local: 172.19.0.252 Logical interface lt-4/3/10.1 (Index 82) (SNMP ifIndex 0) Flags: Point-To-Point SNMP-Traps 0x4000 DLCI 1 Encapsulation: FR-NLPID Input packets : 0 Output packets: 0 Protocol inet, MTU: 4470 Flags: Sendbcast-pkt-to-re Addresses, Flags: Is-Preferred Is-Primary Destination: 172.19.0.252/31, Local: 172.19.0.253 root@svo-e2-mx480-re0# run ping 172.19.0.252 PING 172.19.0.252 (172.19.0.252): 56 data bytes 64 bytes from 172.19.0.252: icmp_seq=0 ttl=64 time=0.069 ms 64 bytes from 172.19.0.252: icmp_seq=1 ttl=64 time=0.039 ms ^C --- 172.19.0.252 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.039/0.054/0.069/0.015 ms {master}[edit] root@svo-e2-mx480-re0# run ping 172.19.0.253 PING 172.19.0.253 (172.19.0.253): 56 data bytes 64 bytes from 172.19.0.253: icmp_seq=0 ttl=64 time=0.353 ms 64 bytes from 172.19.0.253: icmp_seq=1 ttl=64 time=0.295 ms 64 bytes from 172.19.0.253: icmp_seq=2 ttl=64 time=0.303 ms here it is on trio: root@svo-e2-mx480-re0# run show interfaces lt-1/3/0 Physical interface: lt-1/3/0, Enabled, Physical link is Up Interface index: 290, SNMP ifIndex: 699 Type: Logical-tunnel, Link-level type: Logical-tunnel, MTU: Unlimited, Speed: 10000mbps Device flags : Present Running Interface flags: Point-To-Point SNMP-Traps Link flags : None Physical info : 13 Current address: 80:71:1f:94:8a:40, Hardware address: 80:71:1f:94:8a:40 Last flapped : 2011-06-22 19:00:22 UTC (00:00:33 ago) Input rate : 0 bps (0 pps) Output rate : 0 bps (0 pps) Logical interface lt-1/3/0.0 (Index 83) (SNMP ifIndex 701) Flags: Point-To-Point SNMP-Traps 0x4000 DLCI 2 Encapsulation: FR-NLPID Input packets : 0 Output packets: 0 Protocol inet, MTU: 4470 Flags: Sendbcast-pkt-to-re Addresses, Flags: Is-Preferred Is-Primary Destination: 172.19.0.250/31, Local: 172.19.0.250 Logical interface lt-1/3/0.1 (Index 84) (SNMP ifIndex 702) Flags: Point-To-Point SNMP-Traps 0x4000 DLCI 2 Encapsulation: FR-NLPID Input packets : 0 Output packets: 0 Protocol inet, MTU: 4470 Flags: Sendbcast-pkt-to-re Addresses, Flags: Is-Preferred Is-Primary Destination: 172.19.0.250/31, Local: 172.19.0.251 root@svo-e2-mx480-re0# run ping 172.19.0.250 PING 172.19.0.250 (172.19.0.250): 56 data bytes 64 bytes from 172.19.0.250: icmp_seq=0 ttl=64 time=0.068 ms 64 bytes from 172.19.0.250: icmp_seq=1 ttl=64 time=1.052 ms 64 bytes from 172.19.0.250: icmp_seq=2 ttl=64 time=0.040 ms ^C --- 172.19.0.250 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.040/0.387/1.052/0.471 ms {master}[edit] root@svo-e2-mx480-re0# run ping 172.19.0.251 PING 172.19.0.251 (172.19.0.251): 56 data bytes ^C --- 172.19.0.251 ping statistics --- 363 packets transmitted, 0 packets received, 100% packet loss root@svo-e2-mx480-re0# show logical-systems R2-RR interfaces lt-1/3/0 { unit 1 { encapsulation frame-relay; dlci 2; peer-unit 0; family inet { address 172.19.0.251/31; } } } lt-4/3/10 { unit 1 { encapsulation frame-relay; dlci 1; peer-unit 0; family inet { address 172.19.0.253/31; } } } _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
