TestLab Script in AppleScript

August 14th, 2011 No comments

I got a new Mac Pro workstation at work and re-wrote some scripts to work on it. This morning I couldn’t find the script under the new file lay out, it was in /Applications so I decided I had better document the script so I don’t have to rewrite it if I can’t find it.

It uses the same script, tle, that I wrote a while ago, it just fires up iTerm instead of Gnome Terminal.

tell application "iTerm"
    activate
   
    -- If you don't have this you end up with two terminals
    terminate the first session of the first terminal
   
    set iterm to (make new terminal)
   
    repeat with X from 1 to 6
        set Y to "R" & X as string
        tell iterm
            make new session at the end of sessions
            tell the last session
                exec command "/usr/local/bin/tle " & Y & " testlab.chainringcircus.org"
                set name to Y
            end tell
        end tell
    end repeat
   
   
    repeat with X from 1 to 4
        set Y to "SW" & X as string
        tell iterm
            make new session at the end of sessions
            tell the last session
                exec command "/usr/local/bin/tle " & Y & " testlab.chainringcircus.org"
                set name to Y
            end tell
        end tell
    end repeat
   
    repeat with X from 1 to 3
        set Y to "BB" & X as string
        tell iterm
            make new session at the end of sessions
            tell the last session
                exec command "/usr/local/bin/tle " & Y & " testlab.chainringcircus.org"
                set name to Y
            end tell
        end tell
    end repeat
   
    set the bounds of the first window to {0, 0, 1200, 900}
   
end tell

Service Provider Labs

June 9th, 2011 No comments

Running across the Hacking Cisco blog made me remember a similar site, CCIE18473.net. I actually spent about 30 minutes looking for that site and it was Tyson Scott from IPE that me helped find it.

I have added this site to my blogroll even though it is not a blog.

EIGRP MPLS VPN PE-CE SOO

May 31st, 2011 2 comments

I couldn’t resist using all of those acronyms.
EIGRP – Enhanced Interior Gateway Routing Protocol
MPLS – Multiprotocol Label Switching
VPN – Virtual Private Networking
PE-CE – Provider Equipment – Customer Equipment
SOO – Site Of Origin

MPLS SOO
MPLS Fundamentals pp. 220-226

BGP->EIGRP and EIGRP->BGP

Advertisement of the SOO BGP extended community attribute is used to identify routes that have originated from a site so that they are not re-advertised back into the same site. Each SOO uniquely identifies the site and allows for the routes to be filtered. SOO filtering is configured at the interface level. It is commonly used when a site contains both VPN and back door links.

From the Cisco document:
The configuration of the SOO extended community allows MPLS VPN traffic to be filtered on a per-site basis. The SoO extended community is configured in an inbound BGP route map on the PE router and is applied to the interface with the ip vrf sitemap command. The SOO extended community can be applied to all exit points at the customer site for more specific filtering but must be configured on all interfaces of PE routers that provide VPN services to CE routers.

Someone on one of the lists posted about the blog Hacking Cisco so I went over to check it out. Wow. Jarek Rek is the author and he must be putting a ton of time into his studies.

Inspiring.

I have added his blog to the blogroll on the side.
