  • Dynamips and Tap Devices, To and From the same machine

    - by Kyle Brandt
    I am setting up a dynamips/dynagen lab and am wondering if there is any way to get traffic to route out one tap devices, go into the lab, and come back to a tap device on the same machine. I have tried host specific routes as well as removing the route created when I give the tun device an ip via ifconfig. With both of these, traffic always preferes the attached devices and won't go through my lab. Any way to make this work without a separate machine or vm?

  • Dynamips Virtual Router not pinging external host after bridging

    - by maiky
    I have setup a virtual router image with dynamips and setup bridging between tap0 interface of the virtual router and eth0 and br0 with commands [root@cisco_host]# brctl addbr br0 [root@cisco_host]# ifconfig br0 up [root@cisco_host]# ifconfig eth1 0.0.0.0 [root@cisco_host]# brctl addif br0 eth1 [root@cisco_host]# ifconfig br0 192.168.0.100 netmask 255.255.255.0 up In dynagen configuration I have: f0/0 = NIO_tap:tap0 So, [root@cisco_host]# brctl addif br0 tap0 [root@cisco_host]# ifconfig tap0 up router(config)#int fa0/0 router(config-if)#ip address 192.168.0.101 255.255.255.0 router(config-if)#no shutdown After the configuration above I was expecting that from inside the router I could ping an external machine with IP 192.168.0.1 Actually from the host I can ping the external host 192.168.0.1 as well as 192.168.0.100 and 192.168.0.101. So what am I missing here? tap0 is bridged with br0 and in turn with eth1. So why the router is not pingable from 192.168.0.1 and vice-versa??

  • Pasting extended ACL contents into telnet session to Cisco Router SIM

    - by Kyle Brandt
    I have a telnet session to a dynamips router sim. When I try to paste the contents of an actually working ACL retrieved from 'show run' into the access list, only part of gets pasted. The session is something like: enable conf t ip access-list extended Internet <PASTE of Rules> It stops right in the middle of a line: permit tcp any host 123.123.123.123 gt 1 ! should be gt 1023 Anyone know what is happening? The source is an extended access list.
