Basic MPLS Lab on GNS3

Topology:
IOS:  c3640-jk9s-mz.124-16.bin

GNS3 IOS Configuration:

Changed XTERM to gnome-terminal for better copy&paste feature:

In GNS3 Preference , replaced
xterm -T %d -e 'telnet %h %p' >/dev/null 2>&1 &
with
gnome-terminal --command='telnet %h %p' >/dev/null 2>&1 &

Notes:
Cisco MPLS IOS for GNS3
Here are listed working IOS for MPLS LAB on GNS3:
  • c3640-jk9s-mz.124-16
  • c3640-jk9s-mz.124-16a
  • c3640-jk9o3s-mz.123-14.T7
  • c7200-adventerprisek9-mz.124-11.T
  • c3725-adventerprisek9-mz.124-15.T10

Note: c3640-jk9s-mz.124-16是学习Gisco过程中最我们最常用IOS,此IOS不单单支持路由交换实验,同时还支持IPv6、VPN、VOip、MPLS-VPN 等,所以人们通常称之为全能型IOS。
