Routing and switching
Hi all, I have a cisco 2921 router connected to our MPLS Network . our L3 is connected to Router LAN port and 2 other L2 Switches. we hv 10 location across india (MPLS). our dhcp, mail and internet is in UK. we hv an vpn connectivity from our one location to uk. Problem# 1.  I can ping from L3 to Router and other remote (MPLS) location ips.   2.  I can not ping L3 IP from my other remote (MPLS) locations. 3.  I can ping all VLANs on my L3 Switch from my L2 switch. 4.  I can not ping my router from my L2 switch 5. I can not ping my L3 from my RTR. ------------------------------------------------------------------------------ config is as below: L3# ip subnet-zero ip routing ! interface GigabitEthernet0/22  description ***Connected to Switch-2***  switchport trunk encapsulation dot1q  switchport mode trunk ! interface GigabitEthernet0/23  description ***Connected to Switch-1***  switchport trunk encapsulation dot1q  switchport mode trunk ! interface GigabitEthernet0/24  description ***Conneted to MPLS Router***  no switchport  ip address 10.200.101.1 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212  ip directed-broadcast ! interface Vlan1  no ip address  shutdown ! interface Vlan2  description Admin-Vlan  ip address 10.200.102.1 255.255.255.0  ip directed-broadcast ! interface Vlan3  description tuL-Server  ip address 10.200.103.1 255.255.255.0  ip directed-broadcast ! interface Vlan4  description tul-User  ip address 10.200.104.1 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212  ip directed-broadcast ! interface Vlan5  description Wi-Fi  ip address 10.200.105.1 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212  ip directed-broadcast ! interface Vlan6  description kol-User  ip address 10.200.106.1 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212  ip directed-broadcast ! interface Vlan7  description kol-Server  ip address 10.200.107.1 255.255.255.0  ip directed-broadcast ! interface Vlan8  description IPT_Vlan  ip address 11.192.63.1 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212 ! ip default-gateway 12.12.200.146 ip classless ip route 0.0.0.0 0.0.0.0 10.200.101.2 ip http server L2# version 12.2 no service pad service timestamps debug datetime msec service timestamps log datetime msec service password-encryption ip subnet-zero spanning-tree mode pvst spanning-tree extend system-id ! vlan internal allocation policy ascending ! ! ! interface FastEthernet0/1  switchport access vlan 4  switchport mode access  spanning-tree portfast interface GigabitEthernet0/2  description ***Connected to CoreSwitch***  switchport mode trunk ! interface Vlan1  description ***Admin-Vlan***  no ip address  no ip route-cache ! interface Vlan2  description ***Admin-Interface***  ip address 10.200.102.3 255.255.255.0  no ip route-cache RTR# version 15.1 no service pad service tcp-keepalives-in service timestamps debug datetime msec service timestamps log datetime msec service password-encryption no ipv6 cef no ip source-route ip cef ip multicast-routing ! no ip bootp server no ip domain lookup ip domain name ind.mux.com multilink bundle-name authenticated class-map match-any VOICE-RTP  match access-group 110 class-map match-any VOICE-Control  match access-group 111 ! ! policy-map QoS-Policy  class VOICE-RTP  class VOICE-Control  class class-default   fair-queue interface GigabitEthernet0/0  description *****MPLS-4MB*****  ip address 12.12.200.145 255.255.255.252  no ip redirects  no ip unreachables  ip directed-broadcast  no ip proxy-arp  ip flow ingress  load-interval 30  duplex auto  speed auto  service-policy output QoS-Policy interface GigabitEthernet0/1  description ***Local Lan***  ip address 10.200.101.2 255.255.255.0  ip helper-address 11.112.214.105  ip helper-address 11.143.17.212  ip directed-broadcast  ip accounting output-packets  ip pim dense-mode  ip flow ingress   load-interval 30  duplex auto  speed auto router bgp 65525  bgp log-neighbor-changes  network 1.92.145.0 mask 255.255.255.0  network 10.200.102.0 mask 255.255.255.0  network 10.200.103.0 mask 255.255.255.0  network 10.200.104.0 mask 255.255.255.0  network 10.200.105.0 mask 255.255.255.0  network 10.200.106.0 mask 255.255.255.0  network 10.200.107.0 mask 255.255.255.0  network 11.192.63.0 mask 255.255.255.0  neighbor 12.12.200.146 remote-as 7721  neighbor 12.12.200.146 allowas-in 2  no auto-summary ! ip default-gateway 12.12.200.146 ip forward-protocol nd logging history debugging logging facility local6 logging source-interface Loopback0 access-list 110 permit ip any any precedence critical access-list 110 permit ip any any dscp ef access-list 111 permit tcp any any range 2000 2002 access-list 111 permit tcp any any range 11000 11999 end ! !

Thanks. We'll let you know when a new response is added.

As far as I understood your problem, your L3 switch is not able to ping your router :
10.200.101.1 to 10.200.101.2
is that correct ?

that would be the first step to investigate.
If I got it wrong, please let me know.

can you PM me a drawing ? do you have any remote access I can use to help you ?

Best regards
