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。
