Hi,
We have a problem when test IPSEC GRE tunnnel，I want to send a stream into
VPP,and forwarding via ipsec-gre interface,
But VPP hang up, Maybe our configure has something wrong or someting wrong with
ipsec-gre fowarding , can you help me?
our configure as follow:
VPP1
create host-interface name eth2 mac 00:0c:29:6d:b0:82
set interface state host-eth2 up
set interface ip address host-eth2 12.1.1.1/24
ipsec sa add 10 spi 1001 esp crypto-alg aes-cbc-128 crypto-key
4a506a794f574265564551694d653768 integ-alg sha1-96 integ-key
4339314b55523947594d6d3547666b45764e6a58
ipsec sa add 20 spi 1000 esp crypto-alg aes-cbc-128 crypto-key
4a506a794f574265564551694d653768 integ-alg sha1-96 integ-key
4339314b55523947594d6d3547666b45764e6a58
create ipsec gre tunnel src 12.1.1.1 dst 12.1.1.2 local-sa 10 remote-sa 20
set interface state ipsec-gre0 up
create bridge-domain 1
create host-interface name eth3 mac 00:0c:29:6d:b0:8c
set interface state host-eth3 up
set interface l2 bridge host-eth3 1
set interface l2 bridge ipsec-gre0 1
vpp2
create host-interface name eth2 mac 2c:53:4a:03:93:31
create host-interface name eth3 mac 08:57:00:e8:b9:b5
set interface state host-eth2 up
set interface state host-eth3 up
set interface ip address host-eth3 12.1.1.2/24

set interface state ipsec-gre0 up
create bridge-domain 1
set interface l2 bridge host-eth2 1
set interface l2 bridge ipsec-gre0 1
when I send a stream into VPP1 host-eth3, VPP1 hang up, and the call stack as
follow:
VPP# /home/li/vpp18.01/build-data/../src/vnet/fib/ip4_fib.h:107 (ip4_fib_get)
