Specify ttl value:
Specify IP address of GRE tunnel:
esr(config-gre)# ip address 10.10.0.5/24
Switch the GRE tunnel into multipoint mode to be able to connect to multiple points:
esr(config-gre)# multipoint
Proceed to NHRP configuration. Configure multicast to dynamically learnt addresses:
esr(config-gre)# ip nhrp multicast dynamic
Configure the dynamic routing protocol for the Hub. In our example, this will be BGP:
esr(config)# router bgp 65005
esr(config-bgp)# address-family ipv4
esr(config-bgp-af)# neighbor 10.10.0.8
esr(config-bgp-neighbor)# remote-as 65008
esr(config-bgp-neighbor)# enable
esr(config-bgp-neighbor)# exit
esr(config-bgp-af)# neighbor 10.10.0.4
esr(config-bgp-neighbor)# remote-as 65004
esr(config-bgp-neighbor)# enable
esr(config-bgp-neighbor)# exit
esr(config-bgp-af)# enable
Configure IPsec for the Hub:
esr(config)# security ike proposal IKEPROP
esr(config-ike-proposal)# encryption algorithm aes128
esr(config-ike-proposal)# dh-group 2
esr(config-ike-proposal)# exit
esr(config)# security ike policy IKEPOLICY
esr(config-ike-policy)# pre-shared-key ascii-text encrypted 8CB5107EA7005AFF
esr(config-ike-policy)# proposal IKEPROP
esr(config-ike-policy)# exit
esr(config)# security ike gateway IKEGW
esr(config-ike-gw)# ike-policy IKEPOLICY
esr(config-ike-gw)# local address 150.115.0.5
esr(config-ike-gw)# local network 150.115.0.5/32 protocol gre
esr(config-ike-gw)# remote address any
esr(config-ike-gw)# remote network any
esr(config-ike-gw)# mode policy-based
esr(config-ike-gw)# exit
