Hi guys,
I'm testing the static routing. When I configuring static routing in routing
iterations. there is a SIGSEGV.
My configuration and more info is shown below:
configuration:
B 2~180
C 3~181
ip route add 1.1.(C).1/24 via ip4-address 1.1.(B).1
VPP# ip route add 1.1.179.1/24 via ip4-address 1.1.178.1
VPP# ip route add 1.1.180.1/24 via ip4-address 1.1.179.1
VPP# ip route add 1.1.181.1/24 via ip4-address 1.1.180.1
Program received signal SIGSEGV, Segmentation fault.
