設定追加(R1・R2で実施)
- デフォルトで入っている"auto-summary"が入っている
Router1#sh running-config | section router eigrp 1 router eigrp 1 network 10.0.0.0 network 192.168.0.0 auto-summary
- なので"auto-summary"を削除
conf t router eigrp 1 no auto-summary end
- "no auto-summary"できれいさっぱり
Router1#sh running-config | section router eigrp 1 router eigrp 1 network 10.0.0.0 network 192.168.0.0 no auto-summary
