Hi all
I have changed the setup to focus only on the xconnect between Cisco and
Juniper
The topology is simple :
CE1 - Cisco PE - Junos PE - CE2
Please find the outputs
R1#sh mpls ldp neighbor
Peer LDP Ident: 20.20.20.20:0; Local LDP Ident 212.118.1.1:0
TCP connection: 20.20.20.20.646 - 212.118.1.1.23711
State: Oper; Msgs sent/rcvd: 111/92; Downstream
Up time: 00:14:39
LDP discovery sources:
FastEthernet1/0, Src IP addr: 212.118.201.20
Targeted Hello 212.118.1.1 -> 20.20.20.20, active, passive
Addresses bound to peer LDP Ident:
20.20.20.20 212.118.201.20
root# run show l2circuit connections
Layer-2 Circuit Connections:
Legend for connection status (St)
EI -- encapsulation invalid NP -- interface h/w not present
MM -- mtu mismatch Dn -- down
EM -- encapsulation mismatch VC-Dn -- Virtual circuit Down
CM -- control-word mismatch Up -- operational
VM -- vlan id mismatch CF -- Call admission control failure
OL -- no outgoing label IB -- TDM incompatible bitrate
NC -- intf encaps not CCC/TCC TM -- TDM misconfiguration
BK -- Backup Connection ST -- Standby Connection
CB -- rcvd cell-bundle size bad SP -- Static Pseudowire
LD -- local site signaled down RS -- remote site standby
RD -- remote site signaled down XX -- unknown
Legend for interface status
Up -- operational
Dn -- down
Neighbor: 212.118.1.1
Interface Type St Time last up # Up trans
em1.45(vc 45) rmt Up Aug 20 11:15:25 2015 1
Remote PE: 212.118.1.1, Negotiated control-word: No
Incoming label: 299776, Outgoing label: 18
Negotiated PW status TLV: No
Local interface: em1.45, Status: Up, Encapsulation: VLAN
Now , what I have noticed is the MTU on the interfaces (and I think that is
why I cannot ping between the CEs)
R1#show mpls interfaces fastEthernet 1/0 detail | inc MTU
MTU = 1500
R1#sh int f1/1 | inc MTU
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
F1/0 connected to Junos and F1/1 connected to CE
root# run show interfaces em0 | match MTU
Type: Ethernet, Link-level type: Ethernet, MTU: 1514, Speed: 1000mbps
Protocol inet, MTU: 1500
Protocol mpls, MTU: 1500, Maximum labels: 3
Flags: Is-Primary, User-MTU
[edit]
root# run show interfaces em1 | match MTU
Type: Ethernet, Link-level type: Ethernet, MTU: 1518, Speed: 1000mbps
Protocol ccc, MTU: 1518
root# show interfaces em0 | display set
set interfaces em0 unit 0 family inet address 212.118.201.20/24
set interfaces em0 unit 0 family mpls mtu 1500

Mohammad
