[mpls-linux-general] MPLS and ATM

[Jonathan E. <je...@no...>]

Hi James,

Setup is as follows:

Interphase 5575 ATM NIC
Kernel 2.4.3
MPLS v0.990

Basic IP connectivity between the two NICs works fine.  I configure the NICs
thusly:

master)
       atmsigd -b -m network
       atmarpd -b
       sleep 2s

       if [ "$adapter" != "atm$anum" ]; then
          atmarp -c atm$anum
       fi

       ifconfig atm$anum 192.168.1.1 up
       sleep 2s
       atmarp -s 192.168.1.2 0.0.102
       ;;
 slave)
       atmsigd -b
       atmarpd -b
       sleep 2s

       if [ "$adapter" != "atm$anum" ]; then
          atmarp -c atm$anum
       fi

       ifconfig atm$anum 192.168.1.2 up
       sleep 2s
       atmarp -s 192.168.1.1 0.0.102
       ;;

Using the examples in REAME.atm, I can create the labelspace:

root@onc4:~> cat /proc/net/mpls_labelspace
lo      0
teql0   0
atm1    3

But not IN labels:

mpls_add_in_label: enter
mpls_info_default_in_instruction: enter
mpls_info_default_in_instruction: exit
mpls_atm_create_vcc: enter(1,0,33,1)
mpls_atm_create_vcc: adev == NULL
mpls_add_in_label: failed creating vcc
__mpls_del_in_label: enter
__mpls_del_in_label: exit
mpls_add_in_label: exit

or OUT labels:

mpls_add_out_label: enter
mpls_info_default_moi_instruction: enter
mpls_info_default_moi_instruction: exit
mpls_atm_create_vcc: enter(1,0,33,2)
mpls_atm_create_vcc: adev == NULL
mpls_add_out_label: failed to create VCC
__mpls_del_out_label: enter
__mpls_del_out_label: exit
mpls_add_out_label: exit

Cheers!
Jon
