[j-nsp] Juniper MX + Cisco RSVP-TE/LSP

Hello all,



We recently got in to juniper (and my first post here helped solve a
problem we were having, so I am loving this list). I have been trying to
figure out a design issue and hoping this list can help.



The design is this



CORE01.LAX01 (1.1.1.1)

           |

           |

CORE02.LAX01 (1.1.1.2)----------CORE01.ORD01 (2.2.2.1)



What we have is 2 cores in LAX01 (both MX960) and 1 core in ORD01 (Cisco
6500 Sup720-3BXL.



The issue I am having is getting all the LSP and RSVP-TE correct. I get the
LSP between CORE02.LAX01 and CORE01.ORD01 and see it online:



show mpls lsp

Ingress LSP: 2 sessions

To              From            State Rt P     ActivePath       LSPname

Total 2 displayed, Up 2, Down 0



Transit LSP: 0 sessions

Total 0 displayed, Up 0, Down 0



But the LSP between CORE01.LAX01 and CORE01.ORD01 is not showing up:



show mpls lsp

Ingress LSP: 2 sessions

To              From            State Rt P     ActivePath       LSPname

2.2.2.1   1.1.1.1     Dn     0       -                core01.ord01

Total 2 displayed, Up 1, Down 1



Egress LSP: 1 sessions

1.1.1.1     1.1.1.2     Up       0  1 FF       3        - core01.lax01

Total 1 displayed, Up 1, Down 0



Transit LSP: 0 sessions

Total 0 displayed, Up 0, Down 0



Here is my configs. I have been doing some testing and feel like I have
made the configs worse.



jeffn at core02.lax01> show configuration protocols mpls

label-switched-path core01.ord01 {

    to 2.2.2.1;

}

label-switched-path core01.lax01 {

    to 1.1.1.1;

}

interface all;



jeffn at core02.lax01> show configuration protocols rsvp

interface all;



jeffn at core01.lax01> show configuration protocols mpls

label-switched-path core01.ord01 {

    to 2.2.2.1;

}

label-switched-path core02.lax01 {

    to 1.1.1.2;

}

interface all;



jeffn at core01.lax01> show configuration protocols rsvp

interface all;



Sites are all interconnected via a /30.



Here is the config for CORE01.ORD01:



interface Tunnel1

ip unnumbered Loopback0

tunnel destination 1.1.1.1

tunnel mode mpls traffic-eng

tunnel mpls traffic-eng path-option 10 dynamic

!

interface Tunnel2

ip unnumbered Loopback0

ip mtu 9100

tunnel destination 1.1.1.2

tunnel mode mpls traffic-eng

tunnel mpls traffic-eng path-option 10 dynamic



router ospf 1

mpls traffic-eng router-id Loopback0

mpls traffic-eng area 1

Pinging over the LSP from CORE02.LAX01 works fine to CORE01.ORD01

jeffn at core02.lax01 > ping mpls rsvp core01.ord01 sweep

 100! 5052! 7528! 8768! 9388. 9080! 9392. 9236. 9160. 9120. 9100! 9112!
9124. 9120. 9116!

--- lsp ping sweep result---

Maximum Transmission Unit (MTU) is 9116 bytes



Pinging back fails its seems:

core1.ord01#ping mpls traffic-eng tunnel 2

Sending 5, 100-byte MPLS Echos to Tunnel2,

     timeout is 2 seconds, send interval is 0 msec:



Codes: '!' - success, 'Q' - request not transmitted,

       '.' - timeout, 'U' - unreachable,

       'R' - downstream router but not target,

       'M' - malformed request



Type escape sequence to abort.

.....

Success rate is 0 percent (0/5)

core1.ord01#



Also CORE01.LAX01 and CORE02.LAX01 cant ping each other as well:

jeffn at core01.lax01> ping mpls rsvp core02.lax01 detail

Request for seq 1, to interface 196616, no label stack., packet size 92

Timeout for seq 2

Request for seq 5, to interface 196616, no label stack., packet size 92

Timeout for seq 3

Timeout for seq 4

Timeout for seq 5



--- lsping statistics ---

So any help is appreciated.
