HI, First of all why you need certificate. Ask yourself. Does your current company demand for it ? Go for it if company is giving benefit. Do you want to show others what you are upto? Don't go for it. I would suggest better you do something different rather than running behind others. Now a days Cisco certification is of no use, Its all about earning money for cisco. You will easily find theory/lab material on net. Everybody know it. I know atleast 10 people holding these expert certificate since last 6-12 month and doing sam job as they were doing earlier. By talking to them I never felt that they are experts. Now coming back to either SP or RS: It depends upon what experience you hold. If it is at enterprise level SP contents are something new for you so I suggest to go for RS. I would be happy if someone challenge me about my inputs. Regards # mahesh ... View more

Hi Sandeep, Thanks for reply. If I combine top 4 layers (Transport,Session,Presentation,Application) to a single layer and name it application layer then yes I am able to convince myself that BGP is working at application layer and OSPF is working at Layer-3. Regards # Mahesh ... View more

Hello Vishwas, When you announced two prefix to two different peering did you checked reverce trace from route-server (You may find it on traceroute.org website). Based on above trace you may check whether reverce trace is coming back via,. two different path or not. Alternately you may ask PACNET to provide reverse trace from their GW router. Regards ...

Hello, Since your ISP do not allow something like below ip prefix-list POOL1 SEQ 5 permit 199.63.1.0/24 ip prefix-list POOL2 SEQ 5 permit 199.63.3.0/24 route-map LINK1 permit 10 match ip address prefix-list POOL1 ! route-map LINK1 permit 30 match ip address prefix-list POOL2 set as-path prepend 64779 64779 ! route-map LINK1 permit 40 router bgp 64779 neighbor 203.192.137.109 route-map LINK1 out route-map LINK2 permit 10 match ip address prefix-list POOL2 ! route-map LINK2 permit 30 match ip address prefix-list POOL1 set as-path prepend 64779 64779 ! route-map LINK2 permit 40 router bgp 64779 neighbor 203.192.145.49 route-map LINK2 out Regards # Mahesh ...

Hello, It seems you are facing similar issue what we have faced 3-4 times. So far we still not have root cause of this issue but we solved it by recreating sub-interface again. You may try it in maintenance window. Also there is small confusion: From PE2 to PE1 3>Ping to PE2 subinterfaces belonging to VRF ,observed drops.(ping vrf cmd)    >>> does it mean self-ip is also showing drops? from PE1 4>ping to loopback ip using ping mpls PE2_loopback_ip, observed drops.(this is happening in normal hrs also)  >>> this looks bit strange. Can you confirm it again. Regards # mahesh ... View more

Hello, Both of your network (1.0/24 and 3.0/24) are seems to be originating from AS10026 (Pacnet) on internet which means either you are connected to single ISP or prefix from other ISP is not prefered. Few query: 1/ Does this IP (199.63.1.024 and 199.63.3.0/24) was assigned by ISP or did you taken from internet registry. If it belongs to one ISP then other ISP will not accept it, so there is no way you can load share it. 2/ If you are attached to single ISP at two different location (or router) you may try below config. ip prefix-list POOL-HALF-1 SEQ 5 permit 199.63.1.0/25 ip prefix-list POOL-HALF-1 SEQ 10 permit 199.63.3.0/25 ip prefix-list POOL-HALF-2 SEQ 5 permit 199.63.1.128/25 ip prefix-list POOL-HALF-2 SEQ 10 permit 199.63.3.128/25 route-map LINK1 permit 10 match ip address prefix-list POOL-HALF-1 route-map LINK1 permit 30 match ip address prefix-list POOL-HALF-2 set as-path prepend 64779 64779 router bgp 64779 neighbor 203.192.137.109 route-map LINK1 out route-map LINK2 permit 10 match ip address prefix-list POOL-HALF-2 route-map LINK2 permit 30 match ip address prefix-list POOL-HALF-1 set as-path prepend 64779 64779 router bgp 64779 neighbor 203.192.145.49 route-map LINK2 out Let me know if more help/understanding required Regards # Mahesh ...
