Routing

in mpls

what is the difference between include-all and include-any in admin-group

I am confused

and I can't find a kb about this in this site.................

sigh............

r1---gold--r2--gold---r3--slive----r4

if from r1 to r4 ,there is a lsp,include-any gold,can it be up?

Hey Robbie,

 No, it will not be up because there is no 'gold' between r3 and r4 in your example.

 The difference between -any and -all is actually shown in the cli help:

erdems@P-12# set admin-group ? 
Possible completions:
+ apply-groups         Groups from which to inherit configuration data
+ apply-groups-except  Don't inherit configuration data from these groups
+ exclude              Groups, all of which must be absent
+ include-all          Groups, all of which must be present
+ include-any          Groups, one or more of which must be present

 Still following your example, the LSP would be UP if you configure admin-group include-any [ gold silver ], which would mean "include either gold or silver interfaces".

 Cheers,

hi,erdems

thx

would u like to show me one example while include-any work but inclue-all doesn't work

it seems inlcude-any needs all links have one of the color in [color1 color2] and include -all need all links have all colors in [color1 color2]

Hi Rob,

Since you can associate multiple administrative groups to a particular interface, with "include-any" and "include-all" it provides flexibility for user to define the path that LSP can take. These differs much like OR / AND operation.

http://www.juniper.net/techpubs/en_US/junos12.2/topics/usage-guidelines/mpls-configuring-administrative-groups.html

LSP with include-any [gold silver] is a OR operation. Like if the link color is gold or silver, it can be used for path computation.

LSP with include-all [gold-silver] is AND operation. Like only if the link color is both gold and silver, then it can participate in path computation.

Hope this clarifies.

hi,Suray

sorry for the re-comment

if there is a link has blue and red colors

{

include-all red

exclude blue

   }

wheter this link will be choosed,exclude blue while there are 2 colors on this link

Hi Rob,

Include-all has higher precedence than exclude. With "inluce-all red" you have directed to choose only links with colored "red", so it never goes to exclude statement unless you have multi-coloring for the interface.

          
+----+   [R,B]   +----+   [R,B]   +----+   [R,B]   +----+
| R1 |-----------| R2 |-----------| R3 |-----------| R6 |
+----+           +----+           +----+           +----+
   |                                                  |
   |                                                  |
   |             +----+           +----+              |  
   |-------------| R4 |-----------| R5 |--------------|
        [R,S]    +----+    [R]    +----+   [R,S]

Where R is RED admisitrative-group
      B is BLUE admisitrative-group
      S is SILVER admisitrative-group


If the LSP from R1 to R6, is with

    admin-group {
        include-all red;
    }

then it can take either of the path R1-R2-R3-R6 or R1-R4-R5-R6


If the LSP from R1 to R6, is with

    admin-group {
    admin-group {
        include-any red;
        exclude blue;
    }

then the path would be R1-R4-R5-R6


Hope this help.

Hi Rob,

I think I got lost with exclude option. Let's ignore previous post but I have updated accordingly.

Bascially if the LSP from R1 to R6, is with

    admin-group {
    admin-group {
        include-all red;
        exclude blue;
    }

then the path would be R1-R4-R5-R6
