Hi ALL,
I have some questions about Stanford MPLS-TE denmo.
I have build the demo on the web:
http://www.openflow.org/wk/index.php/MPLS-TE_Demo
But I have some problems when I run it ,and I hope someone will be kind to
help me :
Question 1.
Afer generating packets on the hosts, the wireshark cant't capture the packets
on switches except the one derectly connected to the hosts.
For example:
In the h1 xterm do
cd packetgen python packetgen.py 10 1 h1-eth0 3
The host1 connects derectly to s34,and s2 is the only neighbor swith of
s34.The wirsshark can capture the packets on the interface linked to h1,but
can't capture the packets on the other interfaces of s34,neither on all
interfaces of s2. Does this mean that the nox did not send the flow entry to
switch ,or switch didn't install the flow entry in the flow table? And is there
any command to list the flow entry in the modified ovs in the mininet ?
Question 2. How to use the GUI.
When I run the GUI,without generating packets in hosts xterms ,I still can see
the dotted line.What does the dotted line mean? It's a LSP ?If there's no
packets in the network, should there be LSP ?
And I'm concern about how to creat a LSP in the GUI.
Could you give some instructions about how to use the GUI ?
Question 3. About the IP address
In the xterm of h1,the command :python packetgen.py 10 1 h1-eth0 3 means the
src ip address is 192.168.10.x/24 and the dst ip address is 192.168.1.x/24 .But
in mininet ,the hosts's ip is 10.0.0.x/24. How can nox find the src and dst
hosts and caculate the LSP ?
I appreciate it very much if someone could give me some suggestions.
Thanks!
regards
ZhangJin
