Hello vpp list/experts,
Need some suggestion to understand following vnet bonding crash when I
try to ping outside from linux.
Configuration: Linux <==> loopback-ports <==> vpp bridge <==> To outside
Note: No crash happens if I eliminate vnet bonding from steps below.
VPP CLI steps:
============
Summary: Add outbound physical ports eth6 & eth7 into bonding. Create
sub-interfaces with tag 2003, 2001. Create access mode on local-linux
facing interfaces. Add all into L2 bridge.
vpp# create bond mode active-backup
vpp# bond add BondEthernet0 eth6
vpp# bond add BondEthernet0 eth7
vpp# set int state eth6 up
vpp# set int state eth7 up
vpp# set int state BondEthernet0 up
vpp# create sub-interfaces BondEthernet0 2001
vpp# set int state BondEthernet0.2001 up
vpp# create sub-interfaces BondEthernet0 2003
vpp# set int state BondEthernet0.2003 up
vpp# set int l2 bridge BondEthernet0.2001 100
vpp# set int state lbk0 up #A loopback port between linux and VPP
vpp# set int l2 bridge lbk0 100
vpp# set int l2 bridge BondEthernet0.2003 100
vpp# set int state lbk2 up #Another loopback port between linux and VPP
vpp# set int l2 bridge lbk2 100
vpp# set interface l2 tag-rewrite lbk0 push dot1q 2003
vpp# set interface l2 tag-rewrite lbk2 push dot1q 2001
