Konfigurasi Event OSPF Adjacency (Email)

Konfigurasi Event OSPF Adjacency (Email) LAB INI LANJUTAN SAMA SEPERTI LAB SEBELUM SEBELUMNYA Selain event syslog tadi kita juga bisa memanfaatkan EEM ini untuk mengirimkan informasi ke email kita, misalnya OSPF kita down maka, router kita otomatis akan mengirimkan debug ospf ke email kita. Untuk topology masih sama. KONFIG R1 R1(config)#event manager applet OSPF_DOWN R1(config-applet)#event syslog pattern "Nbr 2.2.2.2 on FastEthernet0/0 from FULL to DOWN" R1(config-applet)#action 1.0 cli command "enable" R1(config-applet)#action 2.0 cli command "debug ip ospf adj" R1(config-applet)#action 3.0 mail server "smtp.gmail.com" to "uuqeili@gmail.com" from "R1@idn.id" subject "OSPF IS DOWN" body "Please fix OSPF" R1(config-applet)#exit Untuk Pengecekkan, kita bisa coba debug aja, dan hapus EEM interface down, Dan kita bisa lihat di email kita apa hasilnyaa... selesai
