hello forum guys,
I try to crate dual hub scenario in the lab environment. Spoke 1 register fine with hub 1 and hub 2, spoke 2 register fine but I can cot ping tunnel IP addresses hub 1 and hub2.
Topology:
Here is config:
HUB1:
interface Tunnel1 ip address 10.1.123.1 255.255.255.0 no ip redirects ip mtu 1400 ip rip advertise 10 ip nhrp map multicast dynamic ip nhrp map 10.1.123.4 150.160.0.4 ip nhrp map multicast 150.160.0.4 ip nhrp network-id 101 no ip split-horizon tunnel source FastEthernet1/0.101 tunnel mode gre multipoint end Interface: Tunnel1, IPv4 NHRP Details Type:Hub/Spoke, NHRP Peers:3, # Ent Peer NBMA Addr Peer Tunnel Add State UpDn Tm Attrb ----- --------------- --------------- ----- -------- ----- 1 150.160.0.2 10.1.123.2 UP 00:13:35 D 1 150.160.0.3 10.1.123.3 UP 00:13:34 D 1 150.160.0.4 10.1.123.4 NHRP never S
HUB2:
