利用python生成交换机的VRF配置文件

为了快速生成有规律的VRF，写了一个python脚本，可以快速生成如下的VRF配置。

ip vpn-instance  vpn0
ipv4-family 
route-distinguisher 600:600
vpn-target 600:600 both
quit
quit

#!/usr/bin/python2.7
 
def main():
    f = open('./vrf.txt', 'w')
 
    for i in range(0,500):
        vrf = "vpn"+str(i)
        vlan = 600 + i
 
        f.write("ip vpn-instance  " + vrf + "\n")
        f.write("ipv4-family  " + "\n")
        f.write("route-distinguisher " + str(vlan) + ":" + str(vlan) + "\n")
        f.write("vpn-target " + str(vlan) + ":" + str(vlan) + " both \n")
        f.write("quit " + "\n")
        f.write("quit" + "\n")
        f.write("\r\n")
 
    f.close()
 
if __name__ == '__main__':
    main()

运行后可以理解生成vrf.txt文件。
