Hello,
Just wondering if someone could shed some light on the following scenario please:
Nexus 7018 performing 'show ip route' for a particular destination but shows one valid route and two other routes. However the forwarding table only shows the valid route and the next hops for the 'other' routes, shows the route to the destination originated from the original source... eg
SWITCH# show ip route 10.1.1.250
IP Route Table for VRF "default"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
10.1.1.0/24, ubest/mbest: 1/0
*via 10.1.10.250, Vlan344, [1/0], 6w1d, static
via 192.168.1.78, Eth18/18, [110/62], 6w1d, ospf-1, type-1 <<<<<<<<
via 192.168.1.70, Eth18/17, [110/62], 16w6d, ospf-1, type-1 <<<<<<<<
Forwarding Table is correct:
SWITCH# show forwarding route 10.1.1.250
slot 1
=======
IPv4 routes for table default/base
------------------+------------------+---------------------
Prefix | Next-hop | Interface
------------------+------------------+---------------------
10.1.1.0/24 10.1.10.250 Vlan344
However, when I connect to the devices listed on the show ip route (192.168.1.78 and 70) I get a route pointing back to the switch above.
SWITCH2# show ip route 10.1.1.250
Routing entry for 10.1.1.0/24
Known via "ospf 1", distance 110, metric 21, type extern 1
Last update from 192.168.1.77 on GigabitEthernet1/46, 01:17:51 ago
Routing Descriptor Blocks:
* 192.168.1.77, from 192.168.1.60, 01:17:51 ago, via GigabitEthernet1/46
Route metric is 21, traffic share count is 1
Why would the original switch show these extra two routes when it clearly knows the route to the destination as a Static route?
Regards,
Paul.
