shorten the MPLS IOS commands

when it comes to mpls + vrf we can observe some lengthly commands.. 

R3#show bgp vpnv4 unicast vrf CusA
BGP table version is 7, local router ID is 192.168.254.3
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
              r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path
Route Distinguisher: 65001:100 (default for vrf CusA)
*> 192.168.200.0    192.168.100.1            0             0 65100 i
*>i192.168.210.0    192.168.254.8            0    100      0 65101 i

how to shorten these commands as usual we can use aliases

eg:

alias exec shbgpvrf show bgp vpnv4 unicast vrf

R3#shbgpvrf CusA
BGP table version is 7, local router ID is 192.168.254.3
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
              r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path
Route Distinguisher: 65001:100 (default for vrf CusA)
*> 192.168.200.0    192.168.100.1            0             0 65100 i
*>i192.168.210.0    192.168.254.8            0    100      0 65101 i

eg2: alias exec shvrf show ip route vrf


R3#shvrf CusA

Routing Table: CusA
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, + - replicated route

Gateway of last resort is not set

      192.168.100.0/24 is variably subnetted, 2 subnets, 2 masks
C        192.168.100.0/30 is directly connected, Ethernet0/0
L        192.168.100.2/32 is directly connected, Ethernet0/0
B     192.168.200.0/24 [20/0] via 192.168.100.1, 00:10:08
B     192.168.210.0/24 [200/0] via 192.168.254.8, 00:08:42

l2tpv3 configuration reference

Image
Reference Comparing , Designing and Deploying VPNs chap - 02 : L2TPv3 is the enhanced version of L2TPv2 protocol. Mikrotik uses L2TPv2 i suppose but it offer another similar tunneling mechanism as EOIP. L2TPv3 in cisco provides Pseudo-wire services to the customer. L2TPv3 only require the IP connectivity between peers but it can transport Ethernet, 802.1Q , HDLC, PPP framerelay etc. Advantage over MPLS is the customer having the full control of their routing domain. L2TP depolyment methods having 3 topologies LAC - LNS , LNS - LNS , LAC - LAC Following Diagram explain simple LAC - LAC L2TPv3 setup. It uses two types of messages: control connection messages - used for signaling between LCEs session data messages - Used to transport layer 2 protocols and connections Data channel Message Header having Session ID & cookie to correctly associate with the tunnel Deploying dynamic Pseudowires session 1) configure CEF - Its default in IOSs now. 2) configure a loopback in...

proxy arp

Image
In the above diagram , both hosts don't have default routes. But both are in the same /16 subnet. When host1 tries to ping host2 will it be able to ping ? Yes this behaviour due to the Proxy Arp feature. Note: Cisco by default enabled the proxy arp feature you have to disable it manually . Check the following Debug messages "debug arp" from the router. When the Arp request for 192.168.20.101 received on the router Fa0/1 it replies with its own mac address of fa0/1. (c200.03fc.0001)and vice versa *Mar 1 00:11:43.071: IP ARP: rcvd req src 192.168.12.154 00aa.00f4.6800, dst 192.168.20.101 FastEthernet0/1 *Mar 1 00:11:43.075: IP ARP: sent rep src 192.168.20.101 c200.03fc.0001,dst 192.168.12.154 00aa.00f4.6800 FastEthernet0/1 *Mar 1 00:13:13.067: IP ARP: rcvd req src 192.168.20.101 00aa.0041.1d00, dst 192.168.12.154 FastEthernet0/0 *Mar 1 00:13:13.067: IP ARP: sent rep src 192.168.12.154 c200.03fc.0000, dst 192.168.20.101 00aa.0041.1d00 FastEther...
