Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

Hardware :Dell PowerEdge R630- CPU - CPU E5-2697 v4 , 250GB RAM, 2TB HDD, 1 Network Interface
EVE-NG Running on - Inside ESXI (v6.7)
VT-X - Enabled
promiscuous mode enabled

images:

L2/3 SW: i86bi_linux_l2-adventerprisek9-ms.SSA.high_iron_20190423.bin and i86bi_LinuxL2-AdvEnterpriseK9-M_152_May_2018.bin
Routers: i86bi_LinuxL3-AdvEnterpriseK9-M2_157_3_May_2018.bin , L3-ADVENTERPRISEK9-M-15.4-2T.bin

A simple topology, with one switches and 2 routers.
Router 1 interface e0/1 is connected to Switch 1 interface e0/1.
Router 2 interface e0/2 is connected to Switch 2 interface e0/2.


Sw1 config:
https://omegle.onl/ vshare


interface Ethernet0/1
switchport access vlan 10
switchport mode access
!
interface Ethernet0/2
switchport access vlan 10
switchport mode access
!
vlan 10
name vlan-10


R1 config:

interface Ethernet0/1.10
encapsutation dot1q 10
ip address 10.10.10.1 255.255.255.0
!

R2 config:

interface Ethernet0/1.10
encapsutation dot1q 10
ip address 10.10.10.2 255.255.255.0
!


R1 cannot ping R2.

arp shows incomplete.
disabled cef, same result.

Tried also with Nexus Switch and same result.

Wrong config on the switch:

ports must be

Sw1 config:


interface Ethernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface Ethernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk

rest is ok
