Cisco3650#show ip route xxx.xxx.30.0
Routing entry for xxx.xxx.30.0/24, 2 known subnets
Attached (2 connections)
Variably subnetted with 2 masks
C xxx.xxx.30.0/24 is directly connected, Vlan26
L xxx.xxx.30.1/32 is directly connected, Vlan26
I don't know why that /32 is there. This is odd. I only assigned a /24, not that /32 and I cannot find the /32 anywhere.
Show run looks normal.
Cisco3650#show run int vlan 26
Current configuration : 85 bytes
description Server 26
ip address xxx.xxx.30.1 255.255.255.0
This is happening to all four new VLANs I created last week, all 4 are running Centos 7 servers. That's odd. None of their assigned IPs ping past the first public IP. The rest show this same error.
[root@localhost ~]# ping xxx.xxx.107.59
PING xxx.xxx.107.59 (xxx.xxx.107.59) 56(84) bytes of data.

I tried another Centos 7 server on the same switch, same issue where I can only ping internally the gateway .1 and first public .2, or in this subnet (/29) case, I can ping gateway .129 and main IP .130 but not 132 - 134.

Is this an issue with Centos 7? I tried Google DNS and also the data center's DNS. Same thing (I did 'service network restart' first before re-testing ping).
