Hi, I am trying to do tcp connection between two veth interfaces via switching in VPP, as done in below wiki. The ping is successful, however, the TCP connection failed for a TCP connection from a veth interface in one namespace to another namespace. Tried on http and netcat server. Using latest git master branch. Going to try earlier codes as this seems to be a basic scenarios. Anyone has any quick ideas?
Below are the steps/commands I tried: https://wiki.fd.io/view/VPP/Tutorial_Routing_and_Switching # create namespace ns0 ip netns add ns0 ip link add vpp0 type veth peer name vethns0 ip link set vethns0 netns ns0 ip netns exec ns0 ip link set lo up ip netns exec ns0 ip link set vethns0 up ip netns exec ns0 ip addr add 10.1.1.1/24 dev vethns0 ip link set vpp0 up #create namespace ns1 ip netns add ns1 ip link add vpp1 type veth peer name vethns1 ip link set vethns1 netns ns1 ip netns exec ns1 ip link set lo up ip netns exec ns1 ip link set vethns1 up ip netns exec ns1 ip addr add 10.1.1.2/24 dev vethns1 ip link set vpp1 up # create host-interfaces for vpp0 and vpp1, and assign them to bridge domain 1 vppctl create host-interface name vpp0 vppctl create host-interface name vpp1 vppctl set interface state host-vpp0 up vppctl set interface state host-vpp1 up vppctl set interface l2 bridge host-vpp0 1 vppctl set interface l2 bridge host-vpp1 1 # on HTTP Server terminal root@aurora-vpp-vm1:~# ip netns exec ns1 python -m SimpleHTTPServer 80 Serving HTTP on 0.0.0.0 port 80 ... # on HTTP Client terminal root@aurora-vpp-vm1:~# ip netns exec ns0 wget http://10.1.1.2:80 --2017-02-21 22:01:57-- http://10.1.1.2/ Connecting to 10.1.1.2:80... #also tried netcat, not working either. thanks, Hang
