Subject: [vpp-dev] sub interface after gre doesn't work
please someone attend to this bug. it occurred in multiple scenarios.
1- create gre tunnel between n1--n2
2- add ip and route . it works
3- delete ip and route from gre and delete gre tunnel
4- create sub interface
5- add ip and route.

Fw: [vpp-dev] sub interface after virtual interfaces doesn't work
thanks neal, in this scenario: h1 -- n1 -- n2 -- h2n1,n2: vpp routers. h1,h2: hosts 1- when we remove gre tunnel [ or other virtual interfaces] 2- then adding new sub interface [for connecting n1 to n2 ] we can't ping from h1 to h2.

Re: [vpp-dev] Query regarding CLI handling
hi Damjan,vppsb router plugin used routing table manipulation APIs. is it
needed to do lock in this operations?this functions called when netlink message
arrived.
used APIs: fib_table_entry_deletefib_table_entry_path_remove2
fib_table_entry_updatefib_table_entry_path_add2
is there any documents for safe manipulation of fib tables from plugins?
thanks.

Hi In one of our VPP plugin, we have CLI’s which is used to display some info
and this is time consuming.Thus the main thread, which is busy doing the above,

the CLI handling to a thread other than the main thread ?
Easiest way to address this is to periodically suspend your calculation by
using vlib_process_suspend()that will give chance to other process nodes to do
some work.
Also, please note that all debug CLIs by default are considered thread unsafe,
which means that workerthreads are stopped during their execution and that
typically happens for few hundred microseconds.After making your CLI handler
thread safe, you can specify:
VLIB_CLI_COMMAND (foo_cli_command, static) = {[snip] .is_mp_safe = 1;};
Similar applies to API handlers...
